There is wide agreement that philosophy (from the

But approaches that go beyond such vague characterizations to give a more interesting or profound definition are usually controversial.

, as its sub-disciplines, but the contemporary usage is more narrow.
Some approaches argue that there is a set of essential features shared by all parts of philosophy while others see only weaker family resemblances or contend that it is merely an empty blanket term.
Some definitions characterize philosophy in relation to its method, like pure reasoning. Others focus more on its topic, for example, as the study of the biggest patterns of the world as a whole or as the attempt to answer the big questions.
Both approaches have the problem that they are usually either too wide, by including non-philosophical disciplines, or too narrow, by excluding some philosophical sub-disciplines.
Many definitions of philosophy emphasize its intimate relation to science.
In this sense, philosophy is sometimes understood as a proper science in its own right. Some
naturalist approaches, for example, see philosophy as an empirical yet very abstract science that is concerned with very wide-ranging empirical patterns instead of particular observations.

s.
Science-based definitions usually face the problem of explaining why philosophy in its long history has not made the type of
progress as seen in other sciences.
This problem is avoided by seeing philosophy as an immature or provisional science whose subdisciplines cease to be philosophy once they have fully developed.
In this sense, philosophy is the midwife of the sciences.
Other definitions focus more on the contrast between science and philosophy. A common theme among many such definitions is that philosophy is concerned with
meaning,

One more approach holds that the main task of philosophy is to articulate the pre-ontological understanding of the world, which acts as a

A closely related approach identifies the development and articulation of
worldviews as the principal task of philosophy, i.e. to express how things on the grand scale hang together and which practical stance we should take towards them.

The "Hindu" and "Orthodox" traditions are often contrasted with the "unorthodox" traditions (''nāstika,'' literally "those who reject"), though this is a label that is not used by the "unorthodox" schools themselves. These traditions reject the Vedas as authoritative and often reject major concepts and ideas that are widely accepted by the orthodox schools (such as ''Ātman'', ''Brahman'', and
''Īśvara'').
These unorthodox schools include Jainism (accepts ''ātman'' but rejects ''Īśvara,'' Vedas and ''Brahman''), Buddhism (rejects all orthodox concepts except rebirth and karma),
