Renaissance humanism
The Renaissance ("rebirth") was a period of transition between the Middle Ages and modern thought, in which the recovery of ancient Greek philosophical texts helped shift philosophical interests away from technical studies in logic, metaphysics, and theology towards eclectic inquiries into morality, philology, and mysticism.Frederick Copleston, ''A History of Philosophy, Volume III: From Ockham to Suarez'' (The Newman Press, 1953), p. 18: "When one looks at Renaissance philosophy ... one is faced at first sight with a rather bewildering assortment of philosophies."Brian Copenhaver and Charles Schmitt, ''Renaissance Philosophy'' (Oxford University Press, 1992), p. 4: "one may identify the hallmark of Renaissance philosophy as an accelerated and enlarged interest, stimulated by newly available texts, in primary sources of Greek and Roman thought that were previously unknown or partially known or little read."

In terms of political philosophy, arguments often started from arguing over the first principles of human nature through the thought experiment of what the world would look like without society, a scenario referred to as the state of nature. Hobbes believed that this would be a violent and anarchic, calling life under such a state of affairs "solitary, poor, nasty, brutish and short". To prevent this, he believed that the sovereign of the state should have essentially unlimited power. In contrast, Locke believed the state of nature be one where individuals enjoyed freedom, but that some of that (excluding those covered by natural rights) had to be given up when forming a society, but not to the degree of absolute rule.

The approximate end of the early modern period is most often identified with Immanuel Kant's systematic attempt to limit metaphysics, justify scientific knowledge, and reconcile both of these with morality and freedom.Kenny, ''A New History of Western Philosophy'', vol. 3, p. xiii.Nadler, ''A Companion to Early Modern Philosophy'', p. 3. Whereas the rationalists had believed that knowledge came from ''a priori'' reasoning, the empiricists had argued that it came from ''a posteriori'' sensory experience, Kant aimed to reconcile these views by arguing that the mind uses ''a priori'' understanding to interpret the ''a posteriori'' experiences. He had been inspired to take this approach by the philosophy of Hume, who argued that the mechanisms of the mind gave people the perception of cause and effect.

, advocated by Immanuel Kant, is the view that there are limits on what can be understood since there is much that cannot be brought under the conditions of objective judgment. Kant wrote his '' Critique of Pure Reason'' (1781) in an attempt to reconcile the conflicting approaches of rationalism and empiricism, and to establish a new groundwork for studying metaphysics. Although Kant held that objective knowledge of the world required the mind to impose a conceptual or categorical framework on the stream of pure sensory data—a framework including space and time themselves—he maintained that things-in-themselves existed independently of human perceptions and judgments; he was therefore not an idealist in any simple sense. Kant's account of things-in-themselves is both controversial and highly complex. Continuing his work, Johann Gottlieb Fichte and

Hegel asserts that the twin aims of philosophy are to account for the contradictions apparent in human experience (which arise, for instance, out of the supposed contradictions between "being" and "not being"), and also simultaneously to resolve and preserve these contradictions by showing their compatibility at a higher level of examination ("being" and "not being" are resolved with "becoming").

. Since the usefulness of any belief at any time might be contingent on circumstance, Peirce and James conceptualized final truth as something established only by the future, final settlement of all opinion.
Pragmatism attempted to find a scientific concept of truth that does not depend on personal insight (revelation) or reference to some metaphysical realm. It interpreted the meaning of a statement by the effect its acceptance would have on practice. Inquiry taken far enough is thus the only path to truth.
For Peirce commitment to inquiry was essential to truth-finding, implied by the idea and hope that inquiry is not fruitless. The interpretation of these principles has been subject to discussion ever since. Peirce's maxim of pragmatism is, "Consider what effects, which might conceivably have practical bearings, we conceive the object of our conception to have. Then, our conception of these effects is the whole of our conception of the object."
Critics accused pragmatism falling victim to a simple fallacy: that because something that is true proves useful, that usefulness is an appropriate basis for its truthfulness. Pragmatist thinkers include Dewey,

Since the Second World War, contemporary philosophy has been divided mostly into analytic and Continental philosophy, continental traditions; the former carried in the English speaking world and the latter on the continent of Europe. The perceived conflict between continental and analytic schools of philosophy remains prominent, despite increasing skepticism regarding the distinction's usefulness.
Analytic philosophy
In the English-speaking world, analytic philosophy became the dominant school for much of the 20th century. The term "analytic philosophy" roughly designates a group of philosophical methods that stress detailed argumentation, attention to semantics, use of classical logic and non-classical logic and clarity of meaning above all other criteria. Though the movement has broadened, it was a cohesive school in the first half of the century. Analytic philosophers were shaped strongly by logical positivism, united by the notion that philosophical problems could and should be solved by attention to

Friedrich Ludwig Gottlob Frege (; ; 8 November 1848 – 26 July 1925) was a German philosopher, logician, and mathematician. He was a mathematics professor at the University of Jena, and is understood by many to be the father of analytic ph ...
's ''The Foundations of Arithmetic'' (1884) was the first analytic work, according to Michael Dummett (''Origins of Analytical Philosophy'', 1993). Frege was the first to take 'the linguistic turn,' analyzing philosophical problems through language. He invented a formal notational system for logic. His stance was one of anti-psychologism, arguing that logical truths were independent of the human minds discovering them.
Bertrand Russell and G. E. Moore are also often counted as founders of analytic philosophy. They believed that philosophy should be based on analysing propositions. Russell wrote ''Principia Mathematica'' (with Alfred North Whitehead) to apply this to mathematics, while Moore did the same for ethics with ''Principia Ethica''. Russell's attempts to find a foundation for mathematics led him to Russell's paradox, which caused Frege to abandon logicism. Russell espoused logical atomism, declaring that "logic is the essence of philosophy". In his ''Tractatus Logico-Philosophicus,'' Ludwig Wittgenstein put forward a refined version of this view. Wittgenstein, Russell's 'disciple', argued that the problems of philosophy were simply products of language which were actually meaningless. This was based on the Picture theory of language, picture theory of meaning. Wittgenstein later changed his conception of how language works, arguing instead that it has many different uses, which he called different Language game (philosophy), language games.
Philosophy of science
The logical positivists of the Vienna Circle started as a study group of Russell and Whitehead. They argued that the arguments of metaphysics, ethics and theology were meaningless, as they were not logically or empirically verifiable. This was based on their division of meaningful statements into either the analytic (logical and mathematical statements) and the synthetic (scientific claims). Moritz Schlick and Rudolf Carnap argued that science rested at its roots on direct observation, but Otto Neurath noted that observation already requires theory in order to have meaning. Another participant in the Circle was Carnap's self-confessed disciple, Willard Van Orman Quine. In 'Two Dogmas of Empiricism', Quine criticized the distinction between analytic and synthetic statements. Instead, he advocated for a 'web of belief' approach, whereby all beliefs come from contact with reality (including mathematical ones), but with some being further removed from this contact than others.
Another former participant in the Circle was Karl Popper. He argued that verificationism was logically incoherent, promoting instead Falsifiability, falsificationism as the basis for science. A further advancement in the philosophy of science was made by Imre Lakatos, who argued that negative findings in individual tests did not falsify theories, but rather entire research programmes would eventually fail explain phenomena. Thomas Kuhn further argued that science was composed of paradigms, which would eventually Paradigm shift, shift when evidence accumulated against them. Based on the idea that different paradigms had different meanings of expressions, Paul Feyerabend went further in arguing for

in science.
Philosophy of language
Wittgenstein had first brought up the idea that ordinary language could solve philosophical problems. A loosely associated group of philosophers later became known as practitioners of ordinary language philosophy. It included Gilbert Ryle, J. L. Austin, R. M. Hare, and P. F. Strawson. They believed that as philosophy was not science, it could only be advanced through careful conceptual clarification and connection instead of observation and experimentation. However, they had given up the earlier analytic pursuit of using formal logic to express an Ideal language philosophy, ideal language, but did nevertheless share the scepticism of metaphysical grand theories. Unlike Wittgenstein, they believed only some problems of philosophy to be artifacts of language. This approach has been described as the linguistic turn of analytic philosophy. Ryle introduced the concept of category mistake, which described the misapplication of a concept in the wrong context (which he accused Descartes of doing with the ghost in the machine). One of Austin's key insights was that some language perform a Perlocutionary act, perlocutionary function (creating by themselves an effect on the world), thereby being speech acts. This idea was later taken up by John Searle.
In the final third of the 20th century, philosophy of language emerged as its own programme. The theory of meaning became central to this programme. Donald Davidson (philosopher), Donald Davidson argued that meaning could be understood through a theory of
truth
Truth is the property of being in accord with fact or reality.Merriam-Webster's Online Dictionarytruth 2005 In everyday language, truth is typically ascribed to things that aim to represent reality or otherwise correspond to it, such as belie ...
. This was based on the work of Alfred Tarski. Empirically, Davidson would find the meaning of words in different languages by linking them with the objective conditions of their utterance, which established their truthness. Meaning therefore emerges from the consensus of interpretations of speaker behaviour. Michael Dummett argued against this view on the basis of its Philosophical realism, realism. This was because realism would make the truthness of many sentences beyond measurability. Instead, he argued for verifiability, based on the idea that one could recognise the proof of truth when offered it. Alternative to these, Paul Grice put forward a theory that meaning was based on the intention of the speaker, which over time becomes established after repeated use.
Theories of reference were another major strand of thought on language. Frege had argued that Proper and common nouns, proper names were linked to its referent through a description of what the name refers to. Russell agreed with this, adding that "this" can replace a description in cases of familiarity. Later, Searle and Strawson expanded these ideas by noting that a cluster of descriptions, each of them usable, may be used by linguistic communities. Keith Donnellan further argued that sometimes a description could be wrong but still make the correct reference, this being different from the attributive use of a description. He, as well as Saul Kripke and Hilary Putnam independently, argued that often the referents of proper names are not based on description, but rather on a history of usage passing through users. Towards the end of the century, philosophy of language began to diverge in two directions: the philosophy of mind, and more specific study of particular aspects of language, the latter supported by linguistics.
Philosophy of mind
Early Type physicalism, identity theories of mind in the 1950s and '60s were based on the work of Ullin Place, Herbert Feigl, and J. J. C. Smart. While earlier philosophers such as the Logical Positivists, Quine, Wittgenstein, and Ryle had all used some form of behaviorism to dispense with the mental, they believed that behaviorism was insufficient in explaining many aspects of mental phenomena. Feigl argued that Intentionality, intentional states could not be thus explained. Instead, he espoused externalism. Place meanwhile argued that the mind could be reduced to physical events, while Feigl and Sense agreed they were identical. Functionalism (philosophy of mind), Functionalism in contrast argued that the mind was defined by what it does, rather than what it is based on. To argue against this, John Searle developed the Chinese room thought experiment. Davidson argued for anomalous monism, which claims that while mental events cause physical ones, and the all causal relations are governed by natural laws, there are however no natural laws governing the causality between mental and physical events. This anomaly in the name was explained by supervenience.
In 1970, Keith Campbell (philosopher), Keith Campbell proposed a "new epiphenomenalism", according to which the body produces the mind that does not act on the body, a process which he claims is destined to remain New mysterianism, mysterious. Paul Churchland and Patricia Churchland argued for eliminative materialism, which claims that understanding the brain will lead to a complete understanding of the mind. This was based on developments in neuroscience. However, physicalist theories of mind have had to grapple with the issue of Qualia, subjective experience raised by Thomas Nagel in ''What Is It Like to Be a Bat?'' and Frank Cameron Jackson, Frank Cameron Jackson's so-called knowledge argument. David Chalmers also argued against physicalism in the philosophical zombie argument. He further noted that subjective experience posed the hard problem of consciousness. The inability of physicalist theories to explain conscious feeling has been termed the explanatory gap. In contrast, Daniel Dennett has claimed that no such gap exists as subjective experiences are a 'philosophical fiction'.
Ethics
Ethics in 20th century analytic philosophy has been argued to have began with Moore's ''Principia Ethica''. Moore argued that what is good cannot be defined. Instead, he saw ethical behaviour a result of intuition, which led to non-cognitivism. W. D. Ross in contrast argued that duty formed the basis for ethics.
Russell's meta-ethical thought anticipated emotivism and Moral nihilism, error theory. This was supported by the logical positivists, and later popularised by A. J. Ayer. Charles Stevenson (philosopher), Charles Stevenson also argued that ethical terms were expressions of emotive meanings by speakers. R. M. Hare aimed to expand their meaning from mere expressions, to also being prescriptions which are universalizable. J. L. Mackie supported error theory on the basis that objective values do not exist, as they are Cultural relativism, culturally relative and would be metaphysically strange.
Another strand of ethical thinking began with G. E. M. Anscombe arguing in 1958 that both consequentialism and deontology were based on obligation, which could not function without divine authority, instead promoting virtue ethics. Other notable virtue ethicists included Philippa Foot and Alasdair MacIntyre. The latter combined it with communitarianism.
Other branches
Notable students of Quine include Donald Davidson (philosopher), Donald Davidson and Daniel Dennett. The later work of Russell and the philosophy of Willard Van Orman Quine are influential exemplars of the naturalist approach dominant in analytic philosophy in the second half of the 20th century. But the diversity of analytic philosophy from the 1970s onward defies easy generalization: the naturalism of Quine and his epigoni was in some precincts superseded by a "new metaphysics" of possible worlds, as in the influential work of David Kellogg Lewis, David Lewis. Recently, the experimental philosophy movement has sought to reappraise philosophical problems through social science research techniques.
Some influential figures in contemporary analytic philosophy are: Timothy Williamson, David Kellogg Lewis, David Lewis, John Searle, Thomas Nagel, Hilary Putnam, Michael Dummett, John McDowell, Saul Kripke, Peter van Inwagen, and Patricia Churchland.
Analytic philosophy has sometimes been accused of not contributing to the political debate or to traditional questions in aesthetics. However, with the appearance of ''A Theory of Justice'' by John Rawls and ''Anarchy, State, and Utopia'' by Robert Nozick, analytic political philosophy acquired respectability. Analytic philosophers have also shown depth in their investigations of aesthetics, with Roger Scruton, Nelson Goodman, Arthur Danto and others developing the subject to its current shape.
Continental philosophy
Continental philosophy is a set of 19th- and 20th-century philosophical traditions from mainland Europe. 20th-century movements such as
German idealism

and others are included within this loose category. While identifying any non-trivial common factor in all these schools of thought is bound to be controversial, Michael E. Rosen has hypothesized a few common continental themes: that the natural sciences cannot replace the human sciences; that the thinker is affected by the conditions of experience (one's place and time in history); that philosophy is both theoretical and practical; that metaphilosophy or reflection upon the methods and nature of philosophy itself is an important part of philosophy proper.
The founder of phenomenology, Edmund Husserl, sought to study consciousness as experienced from a first-person perspective, while Martin Heidegger drew on the ideas of Kierkegaard, Nietzsche, and Husserl to propose an unconventional existential approach to ontology.

Conversely, some philosophers have attempted to define and rehabilitate older traditions of philosophy. Most notably, Hans-Georg Gadamer and Alasdair MacIntyre have both, albeit in different ways, revived the tradition of

Existentialism
Existentialism is a term applied to the work of a number of late 19th- and 20th-century philosophers who, despite profound doctrinal differences,''Oxford Companion to Philosophy'', ed. Ted Honderich, New York (1995), page 259. shared the belief that philosophical thinking begins with the human subject—not merely the thinking subject, but the acting, feeling, living human individual. In existentialism, the individual's starting point is characterized by what has been called "the existential attitude", or a sense of disorientation and confusion in the face of an apparently meaningless or absurd world. Many existentialists have also regarded traditional systematic or academic philosophy, in both style and content, as too abstract and remote from concrete human experience.

Phenomenology and hermeneutics
Edmund Husserl's Phenomenology (philosophy), phenomenology was an ambitious attempt to lay the foundations for an account of the structure of conscious experience in general. An important part of Husserl's phenomenological project was to show that all conscious acts are directed at or about objective content, a feature that Husserl called ''intentionality''. Husserl published only a few works in his lifetime, which treat phenomenology mainly in abstract methodological terms; but he left an enormous quantity of unpublished concrete analyses. Husserl's work was immediately influential in Germany, with the foundation of phenomenological schools in Munich (Munich phenomenology) and Göttingen (Göttingen phenomenology). Phenomenology later achieved international fame through the work of such philosophers as Martin Heidegger (formerly Husserl's research assistant and a proponent of hermeneutic phenomenology, a theoretical :wikt:synthesis, synthesis of Hermeneutics#Philosophical hermeneutics, modern hermeneutics and phenomenology), Maurice Merleau-Ponty, and

. Through the work of Heidegger and Sartre, Husserl's focus on subjective experience influenced aspects of existentialism.
Structuralism and post-structuralism
Inaugurated by the linguist Ferdinand de Saussure, structuralism sought to clarify systems of signs through analyzing the discourses they both limit and make possible. Saussure conceived of the sign as being delimited by all the other signs in the system, and ideas as being incapable of existence prior to linguistic structure, which articulates thought. This led continental thought away from humanism, and toward what was termed the decentering of man: language is no longer spoken by man to express a true inner self, but language speaks man.
Structuralism sought the province of a hard science, but its positivism soon came under fire by post-structuralism, a wide field of thinkers, some of whom were once themselves structuralists, but later came to criticize it. Structuralists believed they could analyze systems from an external, objective standing, for example, but the poststructuralists argued that this is incorrect, that one cannot transcend structures and thus analysis is itself determined by what it examines. While the distinction between the signifier and signified was treated as crystalline by structuralists, poststructuralists asserted that every attempt to grasp the signified results in more signifiers, so meaning is always in a state of being deferred, making an ultimate interpretation impossible.
Structuralism came to dominate continental philosophy throughout the 1960s and early 1970s, encompassing thinkers as diverse as Claude Lévi-Strauss, Roland Barthes and Jacques Lacan. Post-structuralism came to predominate from the 1970s onwards, including thinkers such as Michel Foucault, Jacques Derrida, Gilles Deleuze and even Roland Barthes; it incorporated a critique of structuralism's limitations.
Process philosophy
Process philosophy is a tradition beginning with Alfred North Whitehead, who began teaching and writing on process and metaphysics when he joined Harvard University in 1924. This tradition identifies metaphysical reality with Change (philosophy), change.
Process philosophy is sometimes classified as closer to continental philosophy than analytic philosophy, because it is usually only taught in continental departments. However, other sources state that process philosophy should be placed somewhere in the middle between the poles of analytic versus continental methods in contemporary philosophy.

Pyrrho subsequently returned to Greece and founded Pyrrhonism, a philosophy with Similarities between Pyrrhonism and Buddhism, substantial similarities with Buddhism. The Greek biographer Diogenes Laërtius explained that Pyrrho's equanimity and detachment from the world were acquired in India. Pyrrho was directly influenced by Buddhism in developing his philosophy, which is based on Pyrrho's interpretation of the Buddhist

(beliefs about non-evident matters) as the way to reach ataraxia. This is similar to the Buddha's refusal to answer The unanswered questions, certain metaphysical questions which he saw as non-conductive to the path of Buddhist practice and Nagarjuna's "relinquishing of all views (drsti)". Adrian Kuzminski argues for direct influence between these two systems of thought. In ''Pyrrhonism: How the Ancient Greeks Reinvented Buddhism''Adrian Kuzminski (2008), ''Pyrrhonism How the Ancient Greeks Reinvented Buddhism''; for a recent study see Georgios T . Halkias "The Self-immolation of Kalanos and other Luminous Encounters among Greeks and Indian Buddhists in the Hellenistic World" 2015, ''Journal of the Oxford Centre for Buddhist Studies'' 8, 163–186. According to Kuzminski, both philosophies argue against assenting to any dogmatic assertions about an ultimate metaphysical reality behind our sense impressions as a tactic to reach tranquility and both also make use of logical arguments against other philosophies in order to expose their contradictions.
The Cyrenaics, Cyrenaic philosopher Hegesias of Cyrene is thought by some to have been influenced by the teachings of Ashoka's Buddhist missionaries.
Empiricist philosophers, such as David Hume, Hume and George Berkeley, Berkeley, favoured the bundle theory of personal identity. In this theory, the mind is simply 'a bundle of perceptions' without unity. One interpretation of Hume's view of the self, argued for by philosopher and psychologist James Giles (philosopher), James Giles, is that Hume is not arguing for a bundle theory, which is a form of reductionism, but rather for an eliminative view of the self. Rather than reducing the self to a bundle of perceptions, Hume rejects the idea of the self altogether. On this interpretation, Hume is proposing a "Personal identity#The no-self theory, no-self theory" and thus has much in common with
