TOC right Will in philosophy philosophical discussions, like generally in the English language, refers to the desire of an individual, and the acts done when such decisions are put into effect. Actions made according to a person s will are called willing or voluntary . In general the word will does not refer to one desire amongst many however, but the end result, or in other words the choice, decision, or determination which people come to about what they want. The will is in turn important within philosophy because a person s will is one of the most distinct and recognizable aspects or parts of any individual s human mind, along with reason and nous understanding . It is one of the things which makes a person who they are, and it is especially important in ethics , because it the part which determines how people act, at least when they act deliberately. One of the repeating questions discussed throughout all periods of philosophical history is the question of free will which asks how will can be truly free if the actions of people have natural or divine causes which determinism determine them, but which are not really under the control of people. The question is directly connected to discussions of what freedom is, and also the problem of evil , because it brings into question whether people really cause their own acts.

about the concept of sign value as recognized by sociologists and economists numeral signs having additive values Sign value notation a representation of signed numbers in computers Signed number representations In sociology or economics , sign value is the value accorded to an object because of how it impacts the social status of the possessor, as opposed to the value derived from use for its primary purpose. For instance, a potential purchaser may value a Rolls Royce car Rolls Royce limousine partially because it represents a means of transportation and partially because it signifies his wealth to other members of society. The former is the primary function of the limousine giving rise to use value the latter, the sign function.

In logic and mathematics , a truth value , sometimes called a logical value , is a value indicating the relation of a proposition to truth . In classical logic , with its intended semantics, the truth values are true and false that is, classical logic is a two valued logic . Intuitionistic logic lacks a complete set of truth values because its semantics, the Brouwer Heyting Kolmogorov interpretation , is specified in terms of provability conditions, and not directly in terms of the truth of formulae. Multi valued logic s such as fuzzy logic and relevance logic allow for more than two truth values, possibly containing some internal structure. Even non truth valuational logics can associate values with logical formulae, as is done in algebraic semantics . For example, the algebraic semantics of intuitionistic logic is given in terms of Heyting algebra s. Topos theory uses truth values in a special sense the truth values of a topos are the global element s of the subobject classifier . Having truth values in this sense does not make a logic truth valuational.
