Value is a quality that gives things, facts or people an ethical or aesthetic estimate as appropriate in each case and that may be positive or negative .
Being an extremely important issue and widely studied within the field of philosophy is that within this there is a branch that deals only with your case and study: axiology . Basically this will deal with the nature and essence of the value in question.
Regarding its nature, the philosophical currents of Idealism and Materialism propose two well opposed questions. Within Idealism there are two positions, on the one hand Objective Idealism believes that value is outside of people or things, while for Subjective Idealism the value can be found in the consciousness of people.
And on the other hand, Materialism, considers that the nature of value resides and will depend on the ability of each human being to value the world objectively.
On the other hand, values are also used to give us a finished idea of the moral characteristics that people have . Among the most prominent values that most people seek to achieve as a personal goal, we can cite responsibility , humility , solidarity and piety.
The values, in addition, for the society or community in which each human being develops, lives and lives with the rest, are often used to teach about what actions or attitudes to follow and which ones to put aside because they damage the happy coexistence within a society or because they are widely harmful to the development of our neighbor.
At home or at school, many times, values are given as examples of social relationships so that children always learn to act with respect towards each other. Surely, when someone works consistently with one of the values mentioned above, it will be said that that person has values. For this question of the social convention about them it is said that values are also beliefs of the utmost importance, which a culture shares after they have emerged as a consequence of the social convention.
From this will arise the famous scale of values that prevails in each society, which will propose the values going from the most positive to the most negative.
