Discrimination is often understood as acting out of prejudice against persons who differ from us and do not share our views, traits, values or lifestyles. The word "discrimination," however, has an older meaning as well, namely, to draw a clear distinction between proper and improper, good and evil, to differentiate and recognize as different. This older meaning generally carried favorable connotations with it: a person of discrimination was someone of good judgment and detailed knowledge, as in the case of one who could discriminate between fine wines, detecting subtle but relevant differences, or someone on Wall Street who could discriminate between the profiles of different companies, discerning which stocks would rally and which would decline.
