Power is frequently defined by political scientists as the ability to influence the behavior of others with or without resistance. The term authority is often used for power perceived as legitimate by the social structure. Power can be seen as evil or unjust, but the exercise of power is accepted as endemic to humans as social beings. In the corporate environment, power is often expressed as upward or downward. With downward power, a company's superior influences subordinates. When a company exerts upward power, it is the subordinates who influence the decisions of the leader (Greiner & Schein, 1988). Often, the study of power in a society is referred to as politics.

The use of power need not involve coercion (force or the threat of force). At one extreme, it more closely resembles what everyday English-speakers call "influence", although some authors make a distinction between power and influence – the means by which power is used (Handy, C. 1993 Understanding Organisations).

Much of the recent sociological debate on power revolves around the issue of the enabling nature of power. A comprehensive account of power can be found in Steven Lukes Power: A Radical View where he discusses the three dimensions of power. Thus, power can be seen as various forms of constraint on human action, but also as that which makes action possible, although in a limited scope. Much of this debate is related to the works of the French philosopher Michel Foucault (1926–1984), who, following the Italian political philosopher Niccolò Machiavelli (1469–1527), sees power as "a complex strategic situation in a given society social setting". Being deeply structural, his concept involves both constraint and enablement. For a purely enabling (and voluntaristic) concept of power see the works of Anthony Giddens.

Philosophy is the study of general and fundamental problems, such as those connected with reality, existence, knowledge, values, reason, mind, and language. Philosophy is distinguished from other ways of addressing such problems by its critical, generally systematic approach and its reliance on rational argument. The word "philosophy" comes from the Greek φιλοσοφία (philosophia), which literally means "love of wisdom".

The introduction of the terms "philosopher" and "philosophy" has been ascribed to the Greek thinker Pythagoras. The ascription is said to be based on a passage in a lost work of Herakleides Pontikos, a disciple of Aristotle. It is considered to be part of the widespread body of legends of Pythagoras of this time. "Philosopher" was understood as a word which contrasted with "sophist" (from sophoi). Traveling sophists or "wise men" were important in Classical Greece, often earning money as teachers, whereas philosophers are "lovers of wisdom" and not professionals.

The main areas of study in philosophy today include epistemology, logic, metaphysics, ethics, and aesthetics.
