An important scientific innovation rarely makes its way by gradually winning over and converting its opponents: What does happen is that the opponents gradually die out.

Insight must precede application.

Anybody who has been seriously engaged in scientific work of any kind realizes that over the entrance to the gates of the temple of science are written the words: 'Ye must have faith.'

Ego is the immediate dictate of human consciousness.

A new scientific truth is usually not propagated in such a way that opponents become convinced and discard their previous views. No, the adversaries eventually die off, and the upcoming generation is familiarised anew with the truth.

Religion and natural science are fighting a joint battle in an incessant, never-relaxing crusade against skepticism and dogmatism, against disbelief and against superstition, and the rallying cry in this crusade has always been, and will always be, 'On to God.'

It is not the possession of truth, but the success which attends the seeking after it, that enriches the seeker and brings happiness to him.
