An Expert is someone who knows some of the worst mistakes that can be made in his subject and how to avoid them.

Immanuel Kant is proved wrong in his metaphysics by modern science: quantum theory shows that The law of causality no longer applies and the law of conservation of matter is no longer true for the elementary particles.

Physics is grounded in symmetry — we will have to abandon the philosophy of Democritus and the concept of elementary particles. We should accept instead the concept of elementary symmetries.

Plato's elementary particles, at any rate in the Timaeus, are finally not substance but mathematical forms.

Science is where man meets himself, because its object of research is no longer nature in itself but nature exposed to man's questioning.

The Synthetic judgement a priori is a notion that is completely annihilated by the discoveries of our century for the theory of relativity redefined space and time such that the law of causality is no longer applied in quantum theory and the law of conservation of matter is no longer true for the elementary particles.
