1. Kronecker was wrong

Kronecker was quoted often as having said, "God made natural numbers; all else is the work of man".

In my opinion Kronecker did not think correctly, people have created known numbers, but God's numbers are still hidden from us. Men simplify the things because they can only understand step-by-step the very difficult matters.

2. Occam's Razor

Occam's razor is an approach to the understanding of something, which means that “the simplest explanation is usually the correct one”. In another words one should always opt for an explanation in terms of the fewest possible causes, factors, or variables. On the other hand discovery of new and complex thing will be possible if and only if we assume the impossible.
