This framework makes it possible to find the 'truth'. But inevitably there's a severe difficulty, caused by the cultural condition of modern man, who wants answers, grounded on sound fixed facts. This is the essential aim of the modern natural sciences. Their progress in the search for true knowledge is not based on consequently returning to fundamental starting points, but on already obtained knowledge. New facts are added to old facts with the result that the totality continuously increases.
Science is a matter of materialistic cumulation.
Therefore she has to be practiced in a team in which the members complement each other. But philosophy is a matter of clarifying. Real creative philosophy doesn't provide man with ready-made answers in the form of a for all eternity fixed model of reality. On the contrary philosophy is only a continuously searching for the truth. She isn't a matter of collecting truths as many as possible to construct an unchanging model of reality, but she is a never ending intellectual process.
