An analogy compares one thing to another, and is more apt if either 1) the comparison does not rest on trivial attributes, but on essential, and 2) rests on many similarities not just one.
An analogy does not assert that one thing is
exactly like another, but that they are similar in some respects; in this case, using truth or falsity seems inappropriate.
If we conditionally posit that truth is in some sense subjective, or at least has a subjective contributing component, this does not make truth a falsehood
unless one assumes that truth MUST be something different from (or independent of) a subjective one.To say that truth is relative is to present a different definition (or definitions) of it in which the commonly used concepts of truth or falsehood are not applicable (or applicable in each and every case).
Interestingly enough, Nietzsche suggests that at least as far as universal terms are concerned, they are built up by analogy. His example is "leaf" which is made by analogy to all the examples of leaves; to the extent that the universal erases all the variations we see in each leaf, he suggests that it is "false."
