G.W.F. Hegel (1770 – 1831):

“The owl of Minerva spreads its wings only with the falling of the dusk.”

Similar to “vision is 20/20 in hindsight,” [[Hegel]] poetic insight says that philosophers are impotent. Only after the end of an age can philosophers realize what it was about. And by then it’s too late to change things. It wasn’t until the time of Immanuel Kant (1724 – 1804) that the true nature of the Enlightenment was understood, and Kant did nothing to change the Enlightenment; he just consciously perpetuated it.

Marx (1818 – 1883) found Hegel’s apt description to be indicative of the problem with philosophy and responded, “the philosophers have only interpreted the world differently, what matters is to change it.”
