Our soul is cast into a body, where it finds number, time, dimension. Thereupon it reasons, and calls this nature, necessity, and can believe nothing else.

Summary

This quote suggests that human existence is driven by the limitations of the physical world we inhabit. The soul, symbolizing our inner essence, is "cast" into a body that operates within the constructs of number, time, and dimension. As a result, our reasoning abilities develop while perceiving these restrictions as natural and necessary. This view implies that our understanding is limited by these constraints, and we are incapable of believing in anything beyond what is dictated by our physical environment.
