Reason is like an open secret that can become known to anyone at any time; it is the quiet space into which everyone can enter through his own thought

Only then, approaching my fortieth birthday, I made philosophy my life's work.

I began the study of medicine, impelled by a desire for knowledge of facts and of man. The resolution to do disciplined work tied me to both laboratory and clinic for a long time to come.

Philosophy can only be approached with the most concrete comprehension.

Reason is like an open secret that can become known to anyone at any time; it is the quiet space into which everyone can enter through his own thought

Only a development of thought achieved through the self-education of the whole man can prevent any body of thought whatsoever from becoming a poison; can prevent enlightenment from becoming an agent of death.

Philosophic meditation is an accomplishment by which I attain Being and my own self, not impartial thinking which studies a subject with indifference.
