Charles H. Spurgeon on Psalms 94:8

Understand, ye brutish among the people. They said that God did not note, and now, using the same word in the original, the psalmist calls on the wicked to note, and have regard to the truth. He designates them as boors, boarish, swinish men, and well was the term deserved; and he bids them understand or consider, if they can. They thought themselves to be wise, and indeed the only men of wit in the world, but he calls them "boars among the people": wicked men are fools, and the more they know, the more foolish they become. "No fool like a learned fool" is a true proverb. When a man has done with God, he has done with his manhood, and has fallen to the level of the ox and the ass, yea, beneath them, for "the ox knoweth his owner, and the ass his master's crib." Instead of being humbled in the presence of scientific infidels, we ought to pity them; they affect to look clown upon us, but we have far more cause to look down upon them. And ye fools, when will ye be wise? Is it not high time? Ye know the ways of folly, what profit have ye in them? Have ye no relics of reason left? no shreds of sense? If as yet there lingers in your minds a gleam of intelligence, hearken to argument, and consider the questions now about to be proposed to you.
