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.

No burden is so heavy for a man to bear as a succession of happy days.

Science progresses not by convincing the adherents of old theories that they are wrong, but by allowing enough time to pass so that a new generation can arise unencumbered by the old errors.

A scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die and a new generation grows up that is familiar with it.

Scientific discovery and scientific knowledge have been achieved only by those who have gone in pursuit of it without any practical purpose whatsoever in view.

There is no matter as such—mind is the matrix of all matter.

Modern physics has taught us that the nature of any system cannot be discovered by dividing it into its component parts and studying each part by itself... We must keep our attention fixed on the whole and on the interconnection between the parts. The same is true of our intellectual life. It is impossible to make a clear cut between science, religion, and art. The whole is never equal simply to the sum of its various parts.
