Having laid down the mathematical and physical foundations of thought through the theory of
intelligence we have presented scientific natural philosophy and its mathematics briefly but comprehensively.
Since knowledge is dependent on methodology, we have given methodology and epistemology the same
importance although the latter is the core of philosophy by tradition. Being materialist, scientific natural
philosophy relies on rational thought. Therefore, we undertook critique-rectification of mathematics and its
foundations and the methodology of natural science to minimize the inherent uncertainty of thought.
Unlike previous philosophies scientific natural philosophy is far from being speculative based on the most advanced
findings of natural science, particularly, the discovery of the basic constituent of matter, superstring. Its discovery
was the key to our knowledge of the other inhabitants of our universe from micro/quantum through macro/galactic
scales, and from dark through visible matter. For the first time, we know what a black hole and a big bang are. We
are now able to explain wave-particle duality, metal fatigue, elasticity and superconductivity. We know the evolution
of our universe from its birth at Cosmic Burst through its destiny as a cluster of black holes back in dark matter and
the place of our universe in the timeless and boundless Universe – one of the bubbles in it. Moreover, natural laws
are transitory which is quite contrary to traditional thinking. There was no natural law in this part of the Universe
before the Big Bang, and all natural laws will vanish as our universe reaches its destiny.
