“There is a theory which states that if ever anyone discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable. There is another theory which states that this has already happened.”

“It is often stated that of all the theories proposed in this century, the silliest is quantum theory. In fact, some say that the only thing that quantum theory has going for it is that it is unquestionably correct.”

“All significant concepts of the modern theory of the state are secularized theological concepts not only because of their historical development - in which they were transferred from theology to the theory of the state, whereby, for example, the omnipotent god became the omnipotent lawgiver - but also because of their systematic structure, the recognition of which is necessary for a sociological consideration of these concepts. The exception in jurisprudence is analogous to the miracle in theology. Only by being aware of this analogy can we appreciate the manner in which the philosophical ideas of the state developed in the last centuries.”

“It is sometimes said that we should never believe a scientific theory until it is verified by experiment. But a famous astronomer has also stated that we should never believe an observation until it is confirmed by a theory.”

“If faith cannot be reconciled with rational thinking, it has to be eliminated as an anachronistic remnant of earlier stages of culture and replaced by science dealing with facts and theories which are intelligible and can be validated.”

“In its quest to discover how the patterns of reality are organised, the story of modern science hints at a picture of a set of Chinese puzzle boxes, each one more intricately structured and wondrous than the last. Every time the final box appears to have been reached, a key has been found which has opened up another, revealing a new universe even more breathtakingly improbable in its conception. We are now forced to suspect that, for human reason, there is no last box, that in some deeply mysterious, virtually unfathomable, self-reflective way, every time we open a still smaller box, we are actually being brought closer to the box with which we started, the box which contains our own conscious experience of the world. This is why no theory of knowledge, no epistemology, can ever escape being consumed by its own self-generated paradoxes. And this is why we must consider the universe to be irredeemably mystical.”
