"Tautology" has two definitions, one philosophical, one rhetorical. The current article confounds the two definitions.
- From Miriam-Webster, rhetorical tautology is defined as "needless repetition of an idea, statement, or word".
- The triangle example given is not a tautology, but a definition. An example of a rhetorical tautology would be, for instance, a "godless atheist", or a "three-sided triangle" (as opposed to "all triangles have three sides".
- From Dictionary.com, a philosophical tautology is:
a.a compound propositional form all of whose instances are true, as “A or not A.” b.an instance of such a form, as “This candidate will win or will not win.” Another example is "If it rains, it will rain."
"Survival of the fittest" is not a tautology, but a description of a specific process that may be found to be true or untrue via investigation. Tautology is irrelevant here.
Perhaps someone could edit the user page to reflect this. I would, but given my reputation...

Never mind, I did the edit, anyone who wishes to clean it up a little is welcome.--PalMDtalk 14:08, 16 April 2007 (EDT)
