I do not doubt in my heart that there is higher and lower, better and worse.

A person who, looking at the duck-rabbit optical illusion, sees only a duck or only a rabbit has a worse understanding than a person who sees an optical illusion. A person who understands others primarily as instances of categories is morally worse than someone who approaches others as subjectively real persons — as a fellow I, addressed as Thou.

There are others who share my certainty regarding higher and lower and better and worse, but whose ideas of higher and better are lower and worse than mine.

Of course, it is possible that I am wrong. And, of course, if I am wrong, I cannot know it. But it does not follow from this that I must assume skepticism toward my own beliefs. Absolutely not. I will doubt when and only when I arrive at actual doubt, and not a minute before.

Meanwhile, I will fight for what I know to be right against what I know to be wrong, and I will do do with the same fervor and ferocity of those who confuse the artificial clarity of ideology with the natural immediacy of intuitive contact with reality.
