There is no arguing with the pretenders to a divine knowledge and to a divine mission. They are possessed with the sin of pride they have yielded to the perennial temptation.

Knowledge is that possession that no misfortune can destroy no authority can revoke and no enemy can control. This makes knowledge the greatest of all freedoms.

It is not knowledge but the act of learning not possession but the act of getting there which grants the greatest enjoyment.

Knowledge is not eating and we cannot expect to devour and possess what we mean. Knowledge is recognition of something absent it is a salutation not an embrace.

To act on the belief that we possess the knowledge and the power which enable us to shape the processes of society entirely to our liking knowledge which in fact we do not possess is likely to make us do much harm.

There is one quality which one must possess to win and that is definiteness of purpose the knowledge of what one wants and a burning desire to possess it.

I would rather excel in the knowledge of what is excellent than in the extent of my power and possessions.

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.

The possession of knowledge does not kill the sense of wonder and mystery. There is always more mystery.

All the knowledge I possess everyone else can acquire but my heart is all my own.
