[O]ur universe is mathematics in a well-defined sense.

[T]here is a vast literature through the centuries mentioning the bee as a geometer.

I must confess that I was not able to find a way to explain the atomistic character of nature. My opinion is that … one has to find a possibility to avoid the continuum (together with space and time) altogether. But I have not the slightest idea what kind of elementary concepts could be used in such a theory.

I see the most essential thing in the overcoming of the inertial system, a thing that acts upon all processes, but undergoes no reaction. This concept is in principle no better than that of the center of the universe in Aristotelian physics.

I consider it entirely possible that physics cannot be based upon … continuous structures. Then nothing will remain of my whole castle in the air including the theory of gravitation, but also nothing of the rest of contemporary physics.
