Theories
A theory is a systematic and rational form of abstract thinking about a phenomenon, or the conclusions derived from such thinking. It involves contemplative and logical reasoning, often supported by processes such as observation, experimentation, and research. Theories can be scientific, falling within the realm of empirical and testable knowledge, or they may belong to non-scientific disciplines, such as philosophy, art, or sociology. In some cases, theories may exist independently of any formal discipline. In modern science, the term "theory" refers to scientific theories, a well-confirmed type of explanation of nature, made in a way consistent with the scientific method, and fulfilling the criteria required by modern science. Such theories are described in such a way that scientific tests should be able to provide empirical support for it, or empirical contradiction (" falsify") of it. Scientific theories are the most reliable, rigorous, and comprehensive form of scientific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientific Theory
A scientific theory is an explanation of an aspect of the universe, natural world that can be or that has been reproducibility, repeatedly tested and has corroborating evidence in accordance with the scientific method, using accepted protocol (science), protocols of observation, measurement, and evaluation of results. Where possible, theories are tested under controlled conditions in an experiment. In circumstances not amenable to experimental testing, theories are evaluated through principles of abductive reasoning. Established scientific theories have withstood rigorous scrutiny and embody scientific knowledge. A scientific theory differs from a scientific fact: a fact is an observation and a theory organizes and explains multiple observations. Furthermore, a theory is expected to make predictions which could be confirmed or refuted with addition observations. Stephen Jay Gould wrote that "...facts and theories are different things, not rungs in a hierarchy of increasing certai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Falsifiability
Falsifiability (or refutability) is a deductive standard of evaluation of scientific theories and hypotheses, introduced by the Philosophy of science, philosopher of science Karl Popper in his book ''The Logic of Scientific Discovery'' (1934). A Scientific theory, theory or hypothesis is falsifiable if it can be logically contradicted by an empirical test. Popper emphasized the asymmetry created by the relation of a universal law with basic observation statements and contrasted falsifiability to the intuitively similar concept of Verifiability (science), ''verifiability'' that was then current in logical positivism. He argued that the only way to verify a claim such as "All swans are white" would be if one could theoretically observe all swans, which is not possible. On the other hand, the falsifiability requirement for an anomalous instance, such as the observation of a single black swan, is theoretically reasonable and sufficient to logically falsify the claim.

Scientific Method
The scientific method is an Empirical evidence, empirical method for acquiring knowledge that has been referred to while doing science since at least the 17th century. Historically, it was developed through the centuries from the ancient and medieval world. The scientific method involves careful observation coupled with rigorous skepticism, because Philosophy of science#Observation inseparable from theory, cognitive assumptions can distort the interpretation of the Perception#Process and terminology, observation. Scientific inquiry includes creating a testable hypothesis through inductive reasoning, testing it through experiments and statistical analysis, and adjusting or discarding the hypothesis based on the results. Although procedures vary across Branches of science, fields, the underlying #Process, process is often similar. In more detail: the scientific method involves making conjectures (hypothetical explanations), predicting the logical consequences of hypothesis, then ...

Modern Science
The history of science covers the development of science from ancient times to the present. It encompasses all three major branches of science: natural, social, and formal. Protoscience, early sciences, and natural philosophies such as alchemy and astrology that existed during the Bronze Age, Iron Age, classical antiquity and the Middle Ages, declined during the early modern period after the establishment of formal disciplines of science in the Age of Enlightenment. The earliest roots of scientific thinking and practice can be traced to Ancient Egypt and Mesopotamia during the 3rd and 2nd millennia BCE. These civilizations' contributions to mathematics, astronomy, and medicine influenced later Greek natural philosophy of classical antiquity, wherein formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Latin-speaking ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Testable
Testability is a primary aspect of science and the scientific method. There are two components to testability: #Falsifiability or defeasibility, which means that counterexamples to the hypothesis are logically possible. #The practical feasibility of observing a reproducible series of such counterexamples if they do exist. In short, a hypothesis is testable if there is a possibility of deciding whether it is true or false based on experimentation by anyone. This allows anyone to decide whether a theory can be supported or refuted by data. However, the interpretation of experimental data may be also inconclusive or uncertain. Karl Popper introduced the concept that scientific knowledge had the property of falsifiability as published in '' The Logic of Scientific Discovery''.Karl Popper "The Logic of Scientific Discovery", 1934 (as ''Logik der Forschung'', English translation 1959), ISBN 0415278449 and 2002 ISBN 9780415278447, 0415278449 See also * Confirmability * Controlla ...

Reason
Reason is the capacity of consciously applying logic by drawing valid conclusions from new or existing information, with the aim of seeking the truth. It is associated with such characteristically human activities as philosophy, religion, science, language, mathematics, and art, and is normally considered to be a distinguishing ability possessed by humans. Reason is sometimes referred to as rationality. Reasoning involves using more-or-less rational processes of thinking and cognition to extrapolate from one's existing knowledge to generate new knowledge, and involves the use of one's intellect. The field of studies the ways in which humans can use formal reasoning to produce logically valid arguments and true conclusions. Reasoning may be subdivided into forms of logical reasoning, such as deductive reasoning, inductive reasoning, and abductive reasoning. Aristotle drew a distinction between logical discursive reasoning (reason proper), and intuitive reasoning, in whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Causality
Causality is an influence by which one Event (philosophy), event, process, state, or Object (philosophy), object (''a'' ''cause'') contributes to the production of another event, process, state, or object (an ''effect'') where the cause is at least partly responsible for the effect, and the effect is at least partly dependent on the cause. The cause of something may also be described as the reason for the event or process. In general, a process can have multiple causes,Compare: which are also said to be ''causal factors'' for it, and all lie in its past. An effect can in turn be a cause of, or causal factor for, many other effects, which all lie in its future. Some writers have held that causality is metaphysics , metaphysically prior to notions of time and space. Causality is an abstraction that indicates how the world progresses. As such it is a basic concept; it is more apt to be an explanation of other concepts of progression than something to be explained by other more fun ...

Scientific Laws
Scientific laws or laws of science are statements, based on repeated experiments or observations, that describe or predict a range of natural phenomena. The term ''law'' has diverse usage in many cases (approximate, accurate, broad, or narrow) across all fields of natural science (physics, chemistry, astronomy, geoscience, biology). Laws are developed from data and can be further developed through mathematics; in all cases they are directly or indirectly based on empirical evidence. It is generally understood that they implicitly reflect, though they do not explicitly assert, causal relationships fundamental to reality, and are discovered rather than invented. Scientific laws summarize the results of experiments or observations, usually within a certain range of application. In general, the accuracy of a law does not change when a new theory of the relevant phenomenon is worked out, but rather the scope of the law's application, since the mathematics or statement representing t ...

Speculative Reason
The modern division of philosophy into theoretical philosophy and practical philosophyImmanuel Kant, ''Lectures on Ethics'', Cambridge University Press, 2001, p. 41 ("On Universal Practical Philosophy"). Original text: Immanuel Kant, ''Kant’s Gesammelte Schriften'', Band XXVII – Moralphilosophie, 1. Hälfte, 1974p. 243 has its origin in Aristotle's categories of natural philosophy and moral philosophy. The one has theory for its object, and the other practice. __forcetoc__ Overview In Denmark, Finland, Germany, the Netherlands, Sweden, and the United States, courses in theoretical and practical philosophy are taught separately, and are separate degrees. Other countries may use a similar scheme—some Scottish universities, for example, divide philosophy into logic, metaphysics, and ethics—but in most universities around the world philosophy is taught as a single subject. There is also a unified philosophy subject in some Swedish universities, such as Södertörns Högskola ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Classical Greece
Classical Greece was a period of around 200 years (the 5th and 4th centuries BC) in ancient Greece,The "Classical Age" is "the modern designation of the period from about 500 B.C. to the death of Alexander the Great in 323 B.C." ( Thomas R. Martin, ''Ancient Greece'', Yale University Press, 1996, p. 94). marked by much of the eastern Aegean and northern regions of Greek culture (such as Ionia and Macedonia) gaining increased autonomy from the Persian Empire; the peak flourishing of democratic Athens; the First and Second Peloponnesian Wars; the Spartan and then Theban hegemonies; and the expansion of Macedonia under Philip II. Much of the early defining mathematics, science, artistic thought (architecture, sculpture), theatre, literature, philosophy, and politics of Western civilization derives from this period of Greek history, which had a powerful influence on the later Roman Empire. Part of the broader era of classical antiquity, the classical Greek era ended after ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theoria
Christian mysticism is the tradition of mysticism, mystical practices and mystical theology within Christianity which "concerns the preparation [of the person] for, the consciousness of, and the effect of [...] a direct and transformative presence of God in Christianity, God" or divine ''love''. Until the sixth century the practice of what is now called mysticism was referred to by the term ''contemplatio'', c.q. ''theoria'', from ''Contemplation, contemplatio'' (Latin; Ancient Greek, Greek :wikt:θεωρία, θεωρία, ''theoria''), "looking at", "gazing at", "being aware of" God or the divine.William Johnson, ''The Inner Eye of Love: Mysticism and Religion'' (HarperCollins 1997 ), p. 24 Christianity took up ...

Contemplation
In a religious context, the practice of contemplation seeks a direct awareness of the Divinity, divine which Transcendence (religion), transcends the intellect, often in accordance with religious practices such as meditation or contemplative prayer, prayer. Etymology The word ''contemplation'' is derived from the Latin word ''contemplatio'', ultimately from the Latin word ''templum'', a piece of ground consecrated for the taking of auspices, or a building for worship. The latter either derives from the Proto-Indo-European language, Proto-Indo-European root ''*tem-'' ("to cut"), on notion of "place reserved or cut out", or from the root *''temp''- ("to stretch, string"), thus referring to a cleared (measured) space in front of an altar. The Latin word ''contemplatio'' was used to translate the Greek language, Greek word ''θεωρία'' (''theoria, theōría''). Greek philosophy Contemplation was an important part of the philosophy of Plato; Plato thought that through contempl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
