Philosophy

Philosophy is the study of general and fundamental problems, such as those connected with reality , existence, knowledge, values, reason , mind , and language. Philosophy is Template:Wiki from other ways of addressing such problems by its critical, generally systematic approach and its reliance on rational argument. In more casual speech , by extension, "philosophy " can refer to "the most basic beliefs, concepts, and attitudes of an Template:Wiki or group".

The word "philosophy " comes from the Ancient Greek φιλοσοφία (philosophia), which literally means "love of wisdom ". The introduction of the terms "philosopher " and "philosophy " has been ascribed to the Greek thinker Template:Wiki.

Areas of inquiry

Philosophy is divided into many sub-fields. These include epistemology , logic , metaphysics , ethics , and aesthetics. Some of the major areas of study are considered individually below.

Epistemology

Epistemology is concerned with the nature and scope of knowledge , such as the relationships between truth , belief, and theories of Template:Wiki.

Template:Wiki is the position which questions the possibility of completely justifying any truth . The regress argument, a fundamental problem in epistemology , occurs when, in order to completely prove any statement P, its Template:Wiki itself needs to be supported by another Template:Wiki. This chain can do three possible options, all of which are unsatisfactory according to the Template:Wiki. One option is Template:Wiki, where this chain of Template:Wiki can go on forever. Another option is Template:Wiki, where the chain of justifications eventually relies on basic beliefs or axioms that are left unproven. The last option, such as in Template:Wiki, is making the chain circular so that a statement is included in its own chain of Template:Wiki.

Rationalism is the Template:Wiki on Template:Wiki as a source of knowledge . Template:Wiki is the Template:Wiki on observational Template:Wiki via sensory experience over other Template:Wiki as the source of knowledge. Rationalism claims that every possible object of knowledge can be deduced from coherent premises without observation. Template:Wiki claims that at least some knowledge is only a Template:Wiki of observation. For this, Template:Wiki often cites the Template:Wiki of Template:Wiki, where Template:Wiki are not born with mental content and that knowledge builds from experience or perception. Template:Wiki solipsism is the idea that the existence of the world outside the mind is an unresolvable question.

Template:Wiki (fl. 500 BC) argued that it is impossible to doubt that thinking actually occurs. But thinking must have an object, therefore something beyond thinking really exists. Template:Wiki deduced that what really exists must have certain properties—for example, that it cannot come into existence or cease to exist, that it is a coherent whole, that it remains the same eternally (in fact, exists altogether outside time). This is known as the third man argument. Plato (427–347 BC) combined rationalism with a form of realism. The philosopher 's work is to consider being, and the essence (Template:Wiki) of things. But the characteristic of essences is that they are universal . The nature of a man, a triangle, a tree , applies to all men, all triangles, all trees . Plato argued that these essences are mind-Template:Wiki "forms", that humans (but particularly philosophers ) can come to know by reason , and by ignoring the Template:Wiki of sense-perception .

Template:Wiki rationalism begins with Template:Wiki. Template:Wiki on the nature of Template:Wiki experience, as well as scientific discoveries in physiology and optics, led Template:Wiki (and also Locke) to the view that we are directly Template:Wiki of ideas, rather than objects. This view gave rise to three questions:

1. Is an idea a true copy of the real thing that it represents? Sensation is not a direct interaction between bodily objects and our sense, but is a physiological process involving representation (for example, an image on the Template:Wiki). Locke thought that a "secondary quality" such as a sensation of green could in no way resemble the arrangement of Template:Wiki in Template:Wiki that go to produce this sensation , although he thought that "primary qualities" such as shape, size, number, were really in objects.
2. How can physical objects such as chairs and tables, or even Template:Wiki Template:Wiki in the Template:Wiki, give rise to mental items such as ideas? This is part of what became known as the mind -body problem.
3. If all the contents of awareness are ideas, how can we know that anything exists apart from ideas?

Template:Wiki tried to address the last problem by reason . He began, echoing Template:Wiki, with a principle that he thought could not coherently be denied: I think, therefore I am (often given in his original Template:Wiki: Template:Wiki). From this principle, Template:Wiki went on to construct a complete system of knowledge (which involves proving the existence of God , using, among other means, a version of the ontological argument). His view that reason alone could yield substantial truths about reality strongly influenced those philosophers usually considered Template:Wiki rationalists (such as Template:Wiki, Template:Wiki, and Template:Wiki), while provoking criticism from other philosophers who have retrospectively come to be grouped together as Template:Wiki.

Logic

Logic is the study of the Template:Wiki of correct Template:Wiki. Arguments use either deductive reasoning or inductive reasoning. Deductive reasoning is when, given certain statements (called premises), other statements (called conclusions) are unavoidably implied. Rules of inferences from premises include the most popular method, modus ponens, where given “A” and “If A then B”, then “B” must be concluded. A common convention for a Template:Wiki argument is the syllogism. An argument is termed valid if its conclusion does indeed follow from its premises, whether the premises are true or not, while an argument is sound if its conclusion follows from premises that are true. Propositional logic uses premises that are propositions, which are declarations that are either true or false, while predicate logic uses more complex premises called formulae that contain variables. These can be assigned values or can be quantified as to when they apply with the universal quantifier (always apply) or the existential quantifier (applies at least once). Inductive reasoning makes conclusions or generalizations based on probabilistic Template:Wiki. For example, if “90% of humans are right-handed” and “Joe is human” then “Joe is probably right-handed”. Fields in logic include Template:Wiki logic (formal symbolic logic ) and philosophical logic .

Metaphysics

Metaphysics is the study of the most general features of reality , such as existence, time, the relationship between mind and body , objects and their properties, wholes and their parts, events, Template:Wiki, and causation . Traditional branches of metaphysics include cosmology, the study of the world in its entirety, and Template:Wiki, the study of being.

Within metaphysics itself there are a wide range of differing philosophical theories. Template:Wiki, for example, is the belief that reality is mentally constructed or otherwise Template:Wiki while realism holds that reality , or at least some part of it, exists Template:Wiki of the mind . Subjective Template:Wiki describes objects as no more than collections or "bundles" of sense Template:Wiki in the Template:Wiki. The 18th century philosopher Template:Wiki contended that existence is fundamentally tied to perception with the phrase Esse est aut percipi aut percipere or "To be is to be perceived or to Template:Wiki".

In addition to the aforementioned views, however, there is also an ontological Template:Wiki within metaphysics between the concepts of particulars and universals as well. Particulars are those objects that are said to exist in Template:Wiki, as opposed to abstract objects, such as numbers. Universals are properties held by multiple particulars, such as redness or a gender . The type of existence, if any, of universals and abstract objects is an issue of serious debate within metaphysical philosophy . Realism is the philosophical position that universals do in fact exist, while Template:Wiki is the Template:Wiki, or Template:Wiki of universals, abstract objects, or both. Conceptualism holds that universals exist, but only within the mind 's perception .

The question of whether or not existence is a predicate has been discussed since the Early Template:Wiki period. Essence is the set of attributes that make an object what it fundamentally is and without which it loses its identity. Essence is contrasted with accident: a property that the substance has contingently, without which the substance can still retain its identity.
