"At the present time we are so fortunate as to witness the spectacle of the birth, the creation, of a new style of thinking... Sooner or later much will change: the law of causality, the concepts of objectivity and subjectivity. Something else will be demanded from scientific solutions and different problems will be regarded as important. Much that has been proven will be found unproven, and much of what was never proven will turn out to be superfluous."
