Ecclesiastes 1:17

And I gave my heart to know wisdom, and to know madness and folly: I perceived that this also is vexation of spirit.

Ver. 17. And to know madness and folly.] That by comparing of contraries, I might the sooner find and fish out what I sought for. Sed frustra fui, but I disquieted myself in vain. Philosophandum igitur, sed paucis; there is a deceit in philosophy, Col 2:8 and he who chooseth to hold fast this "lying vanity," doth by his own election "forsake his own mercy." Jon 2:8
