Axioms for humans.
08:12pm. In mathematics, there exists a concept of axioms. Axioms are presumptions that have not been or cannot be proved, but form the foundations for other theories and hypothesis. 'The whole is greater than the part' is a good example of mathematical axioms. Something interchangeable can be seen in science, too. In physics, conservation of mass and energy are two theories that cannot be proved. These theories form almost all concepts in science -- from a chemical reaction as simple as combustion to Einstein's famous theories on relativity.
I believe something akin should exist in philosophy. Genetically, all human beings have more than 99.9% of DNA content in common. This commonness can be extended to everything since all matter is composed of only three fundamental particles -- protons, neutrons and electrons. So there must exist axioms for humans, too, right?
