No single theory ever agrees with all the facts in its domain

The only principle that does not inhibit progress is: anything goes.

It is often assumed that science starts from facts and eschews counter-factual theories. Nothing could be further from the truth. What is one of the basic assumptions of the scientific world-view? That the variety of events that surrounds us is held together by a deeper unity.

Ultimate Reality, if such an entity can be postulated, is ineffable.

Copernicanism and other essential ingredients of modern science survived only because reason was frequently overruled in their past.

So far Unitarian realism claiming to possess positive knowledge about Ultimate Reality has succeeded only by excluding large areas of phenomena or by declaring, without proof, that they could be reduced to basic theory, which, in this connection, means elementary particle physics.

Early Chinese thinkers had taken variety at face value. They had favored diversification and collected anomalies instead of trying to explain them away.
