The first thing which I can record concerning myself is that I was born. These are wonderful words. This life to which neither time nor eternity can bring diminution - this everlasting living soul began. My mind loses itself in these depths.

The life of an uneducated man is as useless as the tail of a dog which neither covers its rear end nor protects it from the bites of insects.

Learning is not compulsory... neither is survival.

Neither comprehension nor learning can take place in an atmosphere of anxiety.

Intuition and concepts constitute... the elements of all our knowledge so that neither concepts without an intuition in some way corresponding to them nor intuition without concepts can yield knowledge.

One whose knowledge is confined to books and whose wealth is in the possession of others can use neither his knowledge nor wealth when the need for them arises.

My birth neither shook the German Empire nor caused much of an upheaval in the home. It pleased mother caused father a certain amount of pride and my elder brother the usual fraternal jealousy of a hitherto only son.

The modern mind is in complete disarray. Knowledge has stretched itself to the point where neither the world nor our intelligence can find any foot-hold. It is a fact that we are suffering from nihilism.

That neither our thoughts nor passions nor ideas formed by the imagination exist without the mind is what every body will allow.

However my parents - both of whom came from impoverished backgrounds and neither of whom had been to college took the view that my overactive imagination was an amusing quirk that would never pay a mortgage or secure a pension.
