Original word from Latin "individŭus" which means "indivisible" and its lexical components are, "in" which is a negation, plus the verbal root "dividere" which means "divide". As an adjective it is used to indicate that a particular entity is individual, that is, it cannot be divided. An individual is also defined as a person who is not known by any name, is not expressed or is not meant. Therefore an individual is that living being, whether animal or plant that belongs to a different species from the others.
In biology, unique and homogeneous beings are called individuals, as far as genetics and autonomous in terms of their physiology are concerned, and each one found in a context, both in space and in time. A particular individual is a person who has a series of characteristics, such as name, nationality, culture, among others; He is an autonomous person with his own thoughts, capable of knowing and understanding what he wants and where he is going, an entity with the ability to think before acting; In other words, it is the subject endowed with full religious, ideological, racial and sexual independence and who possesses free will.
In philosophy, specifically in the collectivist current, the use of the word is to define individuals as a fraction of the social order; where each part can be replaceable or replaceable without difficulty. But when speaking of individualism, he completely contradicts this philosophical precept, showing the importance and value of each man, his basic and individual priorities and needs.
