Jeff,

To paraphrase Gertrude, a word is a word, is a word; and a concept is a concept, is a concept. To define one in terms of the other is to engage in a form of circular logic that is nonsense. To use the two words to define each other is the only possible logic. As I originally posted, words represent concepts but they are not concepts themselves.

Jeff, you get a merit badge for vocabulary, but you also get a demerit for gratuitous flaunting. The purpose of posting here is to communicate ideas, foster understanding and stimulate further inquiry, not to obfuscate the subject under discussion.

To contine: a concept is a philosophic and psycho-neurologic predicate used to explain observed phenomena and described by other words. The essence of the scientific method is the identification of similarities and differences. (See: nomenclature and taxonomy)
