Mark Twain:

In promulgating your esoteric cogitations and articulating your superficial, psychological and sentimental observation. Beware of platitudinous ponderosity. Let your extemporaneous decantations, unpremeditated explanations have voracious veracity without any rodomontade and thrasonical bombard. Sedulously, avoid all poly-syllabic profundity, pussilanimous vacuity, pestiferous profanity and similar transgressions.

Elsewhere:

A writer of lyrical rhythms
Encountered a creative schism
When those who spoke terse
Demanded his verse
Lose its sesquipedalianisms.
