The half-promised Melville:
"True, it may be urged that there is nothing a writer of fiction should more carefully see to, as there is nothing a sensible reader will more carefully look for, than that, in the depiction of any character, its consistency should be preserved. But this, though at first blush, seeming reasonable enough, may, upon a closer view, prove not so much so. For how does it couple with another requirement--equally insisted upon, perhaps--that, while to all fiction is allowed some play of invention, yet, fiction based on fact should never be contradictory to it; and is it not a fact, that, in real life, a consistent character is a rara avis? Which being so, the distaste of readers to the contrary sort in books, can hardly arise from any sense of their untrueness. It may rather be from perplexity as to understanding them. But if the acutest sage be often at his wits' ends to understand living character, shall those who are not sages expect to run and read character in those mere phantoms which flit along a page, like shadows along a wall? That fiction, where every character can, by reason of its consistency, be comprehended at a glance, either exhibits but sections of character, making them appear for wholes, or else is very untrue to reality; while, on the other hand, that author who draws a character, even though to common view incongruous in its parts, as the flying-squirrel, and, at different periods, as much at variance with itself as the butterfly is with the caterpillar into which it changes, may yet, in so doing, be not false but faithful to facts.
If reason be judge, no writer has produced such inconsistent characters as nature herself has. It must call for no small sagacity in a reader unerringly to discriminate in a novel between the inconsistencies of conception and those of life as elsewhere. Experience is the only guide here; but as no one man can be coextensive with what is, it may be unwise in every ease to rest upon it. When the duck-billed beaver of Australia was first brought stuffed to England, the naturalists, appealing to their classifications, maintained that there was, in reality, no such creature; the bill in the specimen must needs be, in some way, artificially stuck on."
OK, back to work- quack, quack, chew, chew.
