Argunet Debates

Newton did not use perception to formulate his laws, he lived in an entirely friction prone world. For more complex scientific ideas, their theories and hypothesis are reformulated in the light that the experiemnt has failed, but the theory is still developped sperately from the physical world.

1. Our universe, if it exist, has a core set of objective concepts which can be acquainted without the use of perception. Ethics, the arts and human behaviour are not part of this core set.
2. A scientist can imagine a universe, which he considers similar to ours, and apply the logical laws of physics he has thought up.
3. Because the scientist has no reason to assume that the laws of the universe will change he assumes that the world will behave in the same ways.
4. He can then understand the world by inductive reasoning and predict future things that will happen.
5. Some core properties of our universe which can only be true if logical and do not depend on perception.
