have in common and how to distinguish philosophy from other disciplines. Many different definitions have been proposed but there is very little agreement on which is the right one. Some general characteristics of philosophy are widely accepted, for example, that it is a form of rational inquiry that is systematic, critical, and tends to reflect on its own methods. But such characteristics are usually too vague to give a proper definition of philosophy. Many of the more concrete definitions are very controversial, often because they are revisionary in that they deny the label philosophy to various subdisciplines for which it is normally used. Such definitions are usually only accepted by philosophers belonging to a specific philosophical movement. One reason for these difficulties is that the meaning of the term "philosophy" has changed throughout history: it used to include the

. Others focus on the wideness of its topic, either in the sense that it includes almost every field or based on the idea that it is concerned with the world as a whole or the big questions. These two approaches may also be combined to give a more precise definition based both on method and on topic. Many definitions of philosophy concentrate on its close relation to science. Some see it as a proper science itself, focusing, for example, on the essences of things and not on empirical matters of fact, in contrast to most other sciences, or on its level of abstractness by talking about very wide-ranging empirical patterns instead of particular observations. But since philosophy seems to lack the progress found in regular sciences, various theorists have opted for a weaker definition by seeing philosophy as an immature science that has not yet found its sure footing. This position is able to explain both the lack of progress and the fact that various sciences used to belong to philosophy, while they were still in their provisional stages. It has the disadvantage of degrading philosophical practice in relation to the sciences. Other approaches see philosophy more in contrast to the sciences as concerned mainly with meaning, understanding, or the clarification of language. This can take the form of the analysis of language and how it relates to the world, of finding the

General characteristics and sources of disagreement

carries the term in its title. Modern definitions of philosophy, as discussed in this article, tend to focus on how the term is used today, i.e. on a more narrow sense. Some basic characterizations of philosophy are widely accepted, like that it is a critical and mostly systematic study of a great range of areas. Other such characterizations include that it seeks to uncover fundamental truths in these areas using a reasoned approach while also reflecting on its own methods and standards of evidence. Such characterizations succeed at characterizing many or all parts of philosophy, which is a wide discipline spanning across many fields, as reflected in its sub-disciplines termed "philosophy of...", like the

. One difficulty for this type of approach is that it may include non-philosophical disciplines in its definition instead of distinguishing philosophy from them. To overcome these difficulties, various more specific definitions of philosophy have been proposed. Most of them are controversial. In many cases, they are only accepted by philosophers belonging to one philosophical movement but not by others. The more general conceptions are sometimes referred to as ''descriptive conceptions'' in contrast to the more specific ''prescriptive conceptions''. Descriptive conceptions try to give an account of how the term "philosophy" is actually used or what philosophers in the widest sense do. Prescriptive conceptions, on the other hand, aim at clarifying what philosophy ideally is or what it ought to be, even if what philosophers actually do often fall behind this ideal. This issue is particularly controversial since different philosophical movements often diverge widely in what they consider to be ''good'' philosophy. They are often revisionistic in the sense that many presumed parts of philosophy, past and present, would not deserve the title "philosophy" if they were true. Some definitions of philosophy focus mainly on what the activity of doing philosophy is like, such as striving towards knowledge. Others concentrate more on the theories and systems arrived at this way. In this sense, the terms "philosophy" and "philosophical" can apply both to a thought process, to the results of this activity in the form of theories, or even to contemplative forms of life reflecting such theories. Another common approach is to define philosophy in relation to the task or goal it seeks to accomplish such as answering certain types of questions or arriving at a certain type of knowledge. The difficulty in defining "philosophy" is also reflected in the fact that introductions to philosophy often do not start with a precise definition but introduce it instead by providing an overview of its many branches and subfields, such as
epistemology Epistemology is the branch of philosophy that examines the nature, origin, and limits of knowledge. Also called "the theory of knowledge", it explores different types of knowledge, such as propositional knowledge about facts, practical knowle ...

Outside the academic context, the term "philosophy" is sometimes used in an unspecific sense referring to general ideas or guidelines, such as the business philosophy of a company, the leadership philosophy of an entrepreneur, or the teaching philosophy of a schoolmaster.


Deflationism, essentialism, and family resemblance

An important distinction among definitions of philosophy is between deflationism and
essentialism Essentialism is the view that objects have a set of attributes that are necessary to their Identity (philosophy), identity. In early Western thought, Platonic idealism held that all things have such an "essence"—an Theory of forms, "idea" or "f ...
. The deflationist approach holds that philosophy is an empty blanket term. It is used for convenience by deans and librarians to group various forms of inquiry together. This approach is usually motivated by the enduring difficulties in giving a satisfying definition. According to this view, philosophy does not have a precise
essence Essence () has various meanings and uses for different thinkers and in different contexts. It is used in philosophy and theology as a designation for the property (philosophy), property or set of properties or attributes that make an entity the ...
shared by all its manifestations. One difficulty with the deflationist approach is that it is not helpful for solving disagreements on whether a certain new theory or activity qualifies as philosophy since this would seem to be just a matter of convention. Another is that it implies that the term "philosophy" is rather empty or meaningless. This approach is opposed by essentialists, who contend that a set of features constitutes the essence of philosophy and characterizes all and only its parts. Many of the definitions based on subject matter, method, its relation to science or to meaning and understanding are essentialists conceptions of philosophy. They are controversial since they often exclude various theories and activities usually treated as part of philosophy. These difficulties with the deflationist and the essentialist approach have moved some philosophers towards a middle ground, according to which the different parts of philosophy are characterized by
family resemblance Family resemblance () is a philosophical idea made popular by Ludwig Wittgenstein, with the best known exposition given in his posthumously published book '' Philosophical Investigations'' (1953). It argues that things which could be thought to b ...
s. This means that the various parts of philosophy resemble each other by sharing several features. But different parts share different features with each other, i.e. they do not all share the same features. This approach can explain both that the term "philosophy" has some substance to it, i.e. that it is not just based on an empty convention, and that some parts of philosophy may differ a lot from each other, for example, that some parts are very similar to mathematics while others almost belong to the natural sciences and psychology. This approach has the disadvantage that it leaves the definition of philosophy vague, thereby making it difficult for the non-paradigmatic cases to determine whether they belong to philosophy or not, i.e. that there is no clear-cut distinction.


Based on method and subject matter

Two important aspects for distinguishing philosophy from other disciplines have been its topic or domain of inquiry and its method. The problem with these approaches is usually that they are either too wide, i.e. they include various other disciplines, like empirical sciences or fine arts, in their definition, or too narrow by excluding various parts of philosophy. Some have argued that its method focuses on

knowledge, i.e. that philosophy does not depend on empirical observations and experiments. Instead, such an approach bases philosophical justification primarily on pure

. This way of doing philosophy is often referred to as ''armchair philosophy'' or '' armchair theorizing'' since it can be done from the comfort of one's armchair without any field work. But this characterization by itself is not sufficient as a definition, since it applies equally well to other fields, such as mathematics. Giving a more precise account of the method, for example, as conceptual analysis or phenomenological inquiry, on the other hand, results in a too narrow definition that excludes various parts of philosophy. Definitions focusing on the domain of inquiry or topic of philosophy often emphasize its wide scope in contrast to the individual sciences. According to Wilfrid Sellars, for example, philosophy aims "to understand how things in the broadest possible sense of the term hang together in the broadest possible sense of the term". Similar definitions focus on how philosophy is concerned with the whole of the universe or at least with the big questions regarding life and the world. Such attempts usually result in a definition that is too broad and may include both some natural sciences and some forms of
fine art In European academic traditions, fine art (or, fine arts) is made primarily for aesthetics or creative expression, distinguishing it from popular art, decorative art or applied art, which also either serve some practical function (such as ...

in it. On the other hand, they may also be too narrow, since some philosophical topics concern very specific questions that do not directly deal with the big questions or the world as a whole. Because of these difficulties, philosophers have often tried to combine methodological and topical characterizations in their definitions. This can happen, for example, by emphasizing the wideness of its domain of inquiry, to distinguish it from the other individual sciences, together with its rational method, to distinguish it from fine art and literature. Such approaches are usually more successful at determining the right extension of the term but they also do not fully solve this problem.


Based on relation to science

Various definitions of philosophy emphasize its close relation to science, either by seeing it itself as a
science Science is a systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the universe. Modern science is typically divided into twoor threemajor branches: the natural sciences, which stu ...
or by characterizing the role it plays for science. The plausibility of such definitions is affected by how wide the term "science" is to be understood. If it refers to the

humanities Humanities are academic disciplines that study aspects of human society and culture, including Philosophy, certain fundamental questions asked by humans. During the Renaissance, the term "humanities" referred to the study of classical literature a ...
, such characterizations are less controversial but also less specific. This wide sense is how the term "philosophy" was traditionally used to cover various disciplines that are today considered as distinct disciplines. But this does not reflect its contemporary usage. Many science-based definitions of philosophy face the difficulty of explaining why philosophy has historically not shown the same level of progress as the sciences. Some reject this claim by emphasizing that philosophy has significantly progressed, but in a different and less obvious way. Others allow that this type of progress is not found in philosophy and try to find other explanations why it should still be considered a science.


As a proper science

The strongest relation to science is posited by definitions that see philosophy itself as a science. One such conception of philosophy is found within the phenomenological movement, which sees philosophy as a ''rigorous science''. On this view, philosophy studies the structures of
consciousness Consciousness, at its simplest, is awareness of a state or object, either internal to oneself or in one's external environment. However, its nature has led to millennia of analyses, explanations, and debate among philosophers, scientists, an ...
, more specifically, the essences that show themselves in consciousness and their relations to each other, independent of whether they have instances in the external world. It contrasts with other sciences in that they do not reflect on the essences themselves but research whether and in which ways these essences are manifested in the world. This position was already anticipated by
Arthur Schopenhauer Arthur Schopenhauer ( ; ; 22 February 1788 – 21 September 1860) was a German philosopher. He is known for his 1818 work ''The World as Will and Representation'' (expanded in 1844), which characterizes the Phenomenon, phenomenal world as ...
, who holds that philosophy is only interested in the nature of what there is but not in the

relations explaining why it is there or what will become of it. But this science-based definition of philosophy found in phenomenology has come under attack on various points. On the one hand, it does not seem to be as ''rigorously scientific'' as its proponents proclaim. This is reflected in the fact that even within the phenomenological movement, there are still various fundamental disagreements that the phenomenological method has not been able to resolve, suggesting that philosophy has not yet found a solid

footing. On the other hand, different forms of philosophy study various other topics besides essences and the relations between them. Another conception of philosophy as a science is due to
Willard Van Orman Quine Willard Van Orman Quine ( ; known to his friends as "Van"; June 25, 1908 – December 25, 2000) was an American philosopher and logician in the analytic tradition, recognized as "one of the most influential philosophers of the twentieth century" ...

experience Experience refers to Consciousness, conscious events in general, more specifically to perceptions, or to the practical knowledge and familiarity that is produced by these processes. Understood as a conscious event in the widest sense, experience i ...
s. On this view, both philosophy and mathematics are empirical sciences. They differ from other sciences in that they are more abstract by being concerned with wide-reaching empirical patterns instead of particular empirical observations. But this distance to individual observations does not mean that their claims are non-empirical, according to Quine. A similar outlook in the contemporary discourse is sometimes found in experimental philosophers, who reject the exclusive armchair approach and try to base their theories on experiments. Seeing philosophy as a proper science is often paired with the claim that philosophy has just recently reached this status, for example, due to the discovery of a new philosophical methodology. Such a view can explain that philosophy is a science despite not having made much progress: because it has had much less time in comparison to the other sciences.


As an immature science

But a more common approach is to see philosophy not as a fully developed science on its own but as an immature or preliminary science.
Georg Simmel Georg Simmel (; ; 1 March 1858 – 26 September 1918) was a German sociologist, philosopher, and critic. Simmel was influential in the field of sociology. Simmel was one of the first generation of German sociologists: his neo-Kantian approach ...
, for example, sees it as a provisional science studying appearances. On this view, a field of inquiry belongs to philosophy until it has developed sufficiently to provide exact knowledge of the real elements underlying these appearances.
Karl Jaspers Karl Theodor Jaspers (; ; 23 February 1883 – 26 February 1969) was a German-Swiss psychiatrist and philosopher who had a strong influence on modern theology, psychiatry, and philosophy. His 1913 work ''General Psychopathology'' influenced many ...
gives a similar characterization by emphasizing the deep disagreements within philosophy in contrast to the sciences, which have achieved the status of generally accepted knowledge. This is often connected to the idea that philosophy does not have a clearly demarcated domain of inquiry, in contrast to the individual sciences: the demarcation only happens once a philosophical subdiscipline has reached its full maturity. This approach has the advantage of explaining both the lack of progress in philosophy and the fact that many sciences used to be part of philosophy before they matured enough to constitute fully developed sciences. But the parts that still belong to philosophy have so far failed to reach a sufficient consensus on their fundamental theories and methods. A philosophical discipline ceases to be philosophy and becomes a science once definite knowledge of its topic is possible. In this sense, philosophy is the ''midwife of the sciences''. Philosophy itself makes no progress because the newly created science takes all the credit. On such a view, it is even conceivable that philosophy ceases to exist at some point once all its sub-disciplines have been turned into sciences. An important disadvantage of this view is that it has difficulty in accounting for the seriousness and the importance of the achievements of philosophers, including the ones affecting the sciences. The reason for this is that labeling philosophy as an immature science implies that philosophers are unable to go about their research in the proper manner. Another disadvantage of this conception is that the closeness to science does not fit equally well for all parts of philosophy, especially in relation to
moral A moral (from Latin ''morālis'') is a message that is conveyed or a lesson to be learned from a story or event. The moral may be left to the hearer, reader, or viewer to determine for themselves, or may be explicitly encapsulated in a maxim. ...

. Some even hold that philosophy as a whole may never outgrow its immature status since humans lack the cognitive faculties to give answers based on solid evidence to the philosophical questions they are considering. If this view were true, it would have the serious consequence that doing philosophy would be downright pointless.


Based on meaning, understanding, and clarification

Many definitions of philosophy see as its main task the creation of meaning and
understanding Understanding is a cognitive process related to an abstract or physical object, such as a person, situation, or message whereby one is able to use concepts to model that object. Understanding is a relation between the knower and an object of u ...

, who saw the "clarification of problems and assertions" as the main task of philosophy. According to Moritz Schlick, for example, philosophy is unlike the sciences in that it does not aim at establishing a system of true propositions. Instead, it is the activity of finding meaning. But this activity is nonetheless quite relevant for the sciences since familiarity with the meaning of a proposition is important for assessing whether it is true. A closely related definition is given by
Rudolf Carnap Rudolf Carnap (; ; 18 May 1891 – 14 September 1970) was a German-language philosopher who was active in Europe before 1935 and in the United States thereafter. He was a major member of the Vienna Circle and an advocate of logical positivism. ...
, who sees philosophy as the logic of science, meaning that it is concerned with analyzing scientific concepts and theories. From the perspective of logical atomism, this clarification takes the form of decomposing propositions into basic elements, which are then correlated to the entities found in the world. On this approach, philosophy has both a destructive and a constructive side. Its destructive side focuses on eliminating meaningless statements that are neither verifiable by experience nor true by definition. This position is often connected to the idea that some sentences, such as

, often with the goal of finding a unified science. Other conceptions of philosophy agree that it has to do with finding meaning and clarifying concepts but focus on a wider domain beyond the sciences. For example, a conception commonly found in the analytic tradition equates philosophy with conceptual analysis. In this sense, philosophy has as its main task to clarify the meanings of the terms we use, often in the form of searching for the
necessary and sufficient conditions In logic and mathematics, necessity and sufficiency are terms used to describe a conditional or implicational relationship between two statements. For example, in the conditional statement: "If then ", is necessary for , because the truth of ...

For example, a physicist may study what causes a certain event to happen while a philosopher may study what we mean when using the term "causation". This analysis may be applied to scientific terms but is not limited to them. From the perspective of ordinary language philosophy, philosophy has as its main enterprise the analysis of

, for example, philosophy is not a theory but a practice that takes the form of linguistic therapy. This therapy is important because ordinary language is structured in confusing ways that make us susceptible to all kinds of misunderstandings. It is the task of the philosopher to uncover the root causes of such illusions. This often takes the form of exposing how traditional philosophical "problems" are only pseudo-problems, thereby dissolving them rather than resolving them. So on a theoretical level, philosophy leaves everything as it is without trying to provide new insights, explanations, or deductions. The focus on understanding is also reflected in the transcendental traditions and in some strands of phenomenology, where the task of philosophy is identified with making comprehensible and articulating the understanding we already have of the world, sometimes referred to as pre-understanding or pre-ontological understanding. The need for such an inquiry is expressed in

Others

Other conceptions of philosophy focus on its reflective and metacognitive aspects. One way to emphasize the reflective nature of philosophy is to define it as '' thinking about thinking''. Another characterization of philosophy sometimes found in the literature is that, at least in principle, it does not take any facts for granted and allows any presupposition to be questioned, including its own methods. This is reflected in the fact that philosophy has no solid foundations to build on since whatever foundations one philosopher accepts may be questioned by another.
