We Must Plan For Freedom, And Not

It Must Be Possible For An Empirical System To Be Refuted By Experience.

We Should Therefore Claim, In The Name Of Tolerance, The Right Not To Tolerate The Intolerant.

Thus Science Must Begin With Myths, And With The Criticism Of Myths; Neither With The Collection Of Observations, Nor With The Invention Of Experiments, But With The Critical Discussion Of Myths, And Of Magical Techniques And Practices.

There Will Be Well-testable Theories, Hardly Testable Theories, And Non-testable Theories. Those Which Are Non-testable Are Of No Interest To Empirical Scientists. They May Be Described As Metaphysical.

The Moral Decisions Of Others Should Be Treated With Respect, As Long As Such Decisions Do Not Conflict With The Principle Of Tolerance.
