Many assume it is. We are raised from toddlers never to lie to our parents, our teachers, our friends, or the police. Truth-telling is thus strongly ingrained us culturally. It ensures an unimpeded flow of accurate information among members of a society. It doesn't matter if telling the truth has negative consequences to you or others. TELL the TRUTH! But really, is this even reasonable? How often does "the truth" conflict with being happy? Aren't there some things better left secret? Aren't some people better left in the dark? Can most people even "handle the cold truth?" And what if truth is relative--totally dependent on your point of view? I don't think truth is a value in itself. There is nothing in true statements that make them more moral than false statements. Truth is a property of language. Knowledge of facts is value neutral. Millions of parents lie to their kids every year about Santa Claus to make them happier. Is THAT immoral? No..Truth is only a means towards an end--a tool for a preexisting value. It has no value in itself. That's my tentative proposal.
