Philosophy, as defined by Fichte, is the “science of sciences.” Its aim was to solve the problems of the world. In the past, when all exact sciences were in their infancy, philosophy had to be purely speculative, with little or no regard to realities. But if we regard philosophy as a Mother science, divided into many branches, we find that those branches have grown so large and various, that the Mother science looks like a hen with her little ducklings paddling in a pond, far beyond her reach; she is unable to follow her growing hatchlings. In the meantime, the progress of life and science goes on, irrespective of the cackling of metaphysics. Philosophy does not fulfill her initial aim to bring the results of experimental and exact sciences together and to solve world problems. Through endless, scientific specialization scientific branches multiply, and for want of coordination the great world-problems suffer. This failure of philosophy to fulfill her boasted mission of scientific coordination is responsible for the chaos in the world of general thought. The world has no collective or organized higher ideals and aims, nor even fixed general purposes. Life is an accidental game of private or collective ambitions and greeds.(7)
Systematic study of chemical and physical phenomena has been carried on for many generations and these two sciences now include: (1) knowledge of an enormous number of facts; (2) a large body of natural laws; (3) many fertile working hypotheses respecting the causes and regularities of natural phenomena; and finally (4) many helpful theories held subject to correction by further testing of the hypotheses giving rise to them. When a subject is spoken of as a science, it is understood to include all of the above mentioned parts. Facts alone do not constitute a science any more than a pile of stones constitutes a house, not even do facts and laws alone; there must be facts, hypotheses, theories and laws before the subject is entitled to the rank of a science.
The primal function of a science is to enable us to anticipate the future in the field to which it relates. Judged by this standard, neither philosophy nor its kindred—the so-called social sciences—have in the past been very effective. There was, for example, no official warning of the coming of the World War—the greatest of catastrophes. The future was not anticipated because political philosophers did not possess the necessary basis of knowledge. To be just we must admit that philosophy has been but little aided financially because it is commonly regarded as unnecessary. The technical branches of science have been strongly backed and generally supported by those to whom they have brought direct profit; and so they have had better opportunities for development.
