Nature alone is the master of true genius.

There is no object so large but that at a great distance from the eye it does not appear smaller than a smaller object near.

Be a mirror, absorb everything around you and still remain the same

Although nature commences with reason and ends in experience it is necessary for us to do the opposite, that is to commence with experience and from this to proceed to investigate the reason.

The boundaries of bodies are the least of all things.

One can have no more mastery over the environment, than one has over himself.

Movement will fail sooner than usefulness.
