Definition for Value
From Biology Forums Dictionary
1) The regard that something is held to deserve; the importance, worth, or usefulness of something.
2) Values represent basic convictions that "a specific mode of conduct or end-state of existence is personally or socially preferable to an opposite or converse mode of conduct or end-state of existence." They contain a judgmental element in that they carry an individual's ideas as to what is right, good, or desirable. Values have both content and intensity attributes. The content attribute says a mode of conduct or end-state of existence is important. The intensity attribute specifies how important it is. When we rank an individual's values in terms of their intensity, we obtain that person's value system.
