“I've tested my strength everywhere. You advised me to do that, "in order to know myself." This testing for myself, and for show, proved it to be boundless, as before all my life. In front of your very eyes I endured a slap from your brother; I acknowledged my marriage publicly. But what to apply my strength to--that I have never seen, nor do I see it now, despite your encouragements in Switzerland, which I believed. I am as capable now as ever before of wishing to do a good deed, and I take pleasure in that; along with it, I wish for evil and also feel pleasure. But both the one and the other, as always, are too shallow, and are never very much. My desires are far too weak; they cannot guide. One can cross a river on a log, but not on a chip.”
