“In music, sometimes a man will feel that he comes to the edge of breaking out from prison bars of existence, breaking out from the universe altogether. There is a sense that the goal is at hand; that the boundary wall of the universe is crumbling and will be breached at the next moment, when the soul will pass out free into the infinite.””

“When the self is not engaged in apprehending objects it becomes aware of itself.””

“Spinoza formulated the profoundly important principle that *all determination is negation*. To determine a thing is to cut it off from some sphere of being and so to limit it. To define is to set boundaries. To say that a thing is green limits it by cutting it from the sphere of pink, blue, or other-coloured things. To say that it is good cuts it off from the sphere of evil. This limitation is the same as negation. To *affirm* that a thing is within certain limits is to *deny* that it is outside those limits. To say that it is green is to say that it is not pink. Affirmation involves negation. Whatever is said of a thing denies something else of it. All determination is negation.This principle is fundamental for Hegel also, but with him it takes rather the converse form that *all negation is determination*. Formal logicians will remind us that we cannot simply convert Spinoza's proposition. But it is sufficient to point out in reply that not only does affirmation involve negation; negation likewise involves affirmation. To say that a thing belongs to one class is to affirm that it belongs to some other class,”
