We live in a world in which analysis is performed in a logical framework. Every question which we can answer is answered with a unique answer.
Solutions are contradictory.
For every one who sees clearly that a stock share should be sold, there is another one to whom it is obvious that the shares should be bought. For every Pro there is a Con. Probabilistic situations are non-deterministic. But physicists have converted those problems to deterministic ones by restricting answers to descriptions of the range and frequency of those results. Darwinian Laws or Mendelian Laws of genetics appear as deterministic tools, but they are broken if they are taken to apply in single instances.
