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.

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

The only absolute truth is that there are no absolute truths.

Mathematical Reasoning is not only exact; it has its own criteria of reality.

Events and developments, such as ... the Copernican Revolution, ... occurred only because some thinkers either decided not to be bound by certain "obvious" methodological rules, or because they unwittingly broke them.

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.

Confronted with such a variety most philosophers try to establish one approach to the exclusion of all others. As far as they are concerned there can only be one true way- and they want to find it. Thus normative philosophers argue that knowledge is a result of the application of certain rules, they propose rules which in their opinion constitute knowledge and reject what clashes with them.
