Every individual, when he looks within, recognises in his nature, which is his will, the thing in itself, therefore that which everywhere alone is real.

Context

“I believe I have given, in the first four [pg 417] chapters of this fourth book of the supplements, an adequate introduction to such knowledge. What is said above may further be illustrated in the following manner. Every individual, when he looks within, recognises in his nature, which is his will, the thing in itself, therefore that which everywhere alone is real. Accordingly he conceives himself as the kernel and centre of the world, and regards himself as of infinite importance. If, on the other hand, he looks without, then he is in the province of the idea the mere phenomenon, where he sees himself as an individual among an infinite number of other individuals, accordingly as something very insignificant, nay, vanishing altogether.” source
