“There continue to be complex debates about what Nietzsche understood truth to be. Quite certainly, he did not think, in pragmatist spirit, that beliefs are true if they serve our interests or welfare: we have just seen some of his repeated denials of this idea. The more recently fashionable view is that he was the first of the deniers, thinking that there is no such thing as truth, or that truth is what anyone thinks it is, or that it is a boring category that we can do without. This is also wrong, and more deeply so. Nietzsche did not think that the ideal of truthfulness went into retirement when its metaphysical origins were discovered, and he did not suppose, either, that truthfulness could be detached from a concern for the truth. Truthfulness as an ideal retains its power, and so far from his seeing truth as dispensable or malleable, his main question is how it can be made bearable.”

Context: It is mankind's discovery of language which more than any other single thing has separated him from the animal creation. Without language, what concept have we of past or future as separated from the immediate present? Without language, how can we tell anyone what we feel, or what we think? It might be said that until he developed language, man had no soul, for without language how could he reach deep inside himself and discover the truths that are hidden there, or find out what emotions he shared, or did not share, with his fellow men and women. But because this greatest gift of all gifts is in daily use, and is smeared, and battered and trivialized by commonplace associations, we too often forget the splendour of which it is capable, and the pleasures that it can give, from the pen of a master.

Context: For any community and those living in it, only that is true which can be communicated to all. Hence universal communicability is unconsciously accepted as the source and criterion of those truths that promote life through communal means. Truth is that which our conventional social code accepts as effective in promoting the purposes of the group. … This community will condemn as a “liar” the person who misuses its unconsciously accepted, and therefore valid, metaphors. … Community members are obliged to “lie” in accordance with fixed convention. To put it otherwise, they must be truthful by playing with the conventionally marked dice. To fail to pay in the coin of the realm is to tell forbidden lies, for, on this view, whatever transcends conventional truth is a falsehood. To tell lies of this kind is to sacrifice the world of meanings upon which the endurance of his community rests. Conversely, there are forbidden truths: This same threat to the continuance of the community is also counteracted by relentlessly preventing anyone from thinking and uttering unconventional but authentic truths.

Context: Socrates is not just expounding noble ideas in a vacuum. He is in the middle of a war between those who think truth is absolute and those who think truth is relative. He is fighting that war with everything he has. The Sophists are the enemy.
Now Plato's hatred of the Sophists makes sense. He and Socrates are defending the Immortal Principle of the Cosmologists against what they consider to be the decadence of the Sophists. Truth. Knowledge. That which is independent of what anyone thinks about it. The ideal that Socrates died for. The ideal that Greece alone possesses for the first time in the history of the world. It is still a very fragile thing. It can disappear completely. Plato abhors and damns the Sophists without restraint, not because they are low and immoral people—there are obviously much lower and more immoral people in Greece he completely ignores. He damns them because they threaten mankind's first beginning grasp of the idea of truth. That's what it is all about.
