“And for the authentical truth of either person or actions, who (worth the respecting) will expect it in a poem, whose subject is not truth, but things like truth? Poor envious souls they are that cavil at truth's want in these natural fictions; material instruction, elegant and sententious excitation to virtue, and deflection from her contrary, being the soul, limbs, and limits of an authentical tragedy.”

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: There is only one Art, whose sole criterion is the power, the authenticity, the revelatory insight, the courage and suggestiveness with which it seeks its truth. … Thus, from the standpoint of the work and its worth it is irrelevant to which political ideas the artist as a citizen claims allegiance, which ideas he would like to serve with his work or whether he holds any such ideas at all.
