Quote from ‘The Fourth Curiosity’
But to say that a singular is known by sense is a confusion of thought. It is not known by the feeling-element of sense, but by the compulsion, the insistency, that characterizes experience. For the singular subject is real; and reality is insistency. That is what we mean by “reality.” It is the brute irrational insistency that forces us to acknowledge the reality of what we experience, that gives us our conviction of any singular.
