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

For in much wisdom is much grief: and he that increaseth knowledge increaseth sorrow.

--Ecclesiastes 1.17-18



. . .those who proceed like plundering soldiers: they pick up a few things they can use, soil and confuse the rest, and blaspheme the whole.

--Friedrich Nietzsche
