VII. Modern Man and His World Conception

Carneri's mode of conception is entirely in agreement with the idea of evolution that does not permit the notion that a later phase of development is already pre-formed in an earlier one, but considers it as a really new formation. The chemical process does not contain implicitly animal life, and happiness develops as an entirely new element on the ground of the animal's instinct for self-preservation. The difficulty that lies in this thought caused a penetrating thinker, W. H. Rolph, to develop the line of reasoning that he set down in his book, Biological Problems, an Attempt at the Development of a Rational Ethics (1884). Rolph asks himself, “What is the reason that a form of life does not remain at a given stage but develops progressively and becomes more perfect?” This problem presents no difficulty for a thinker who maintains that the later form is already implicitly contained in the earlier one. For him, it is quite clear that what is at first implicit will become explicit at a certain time. But Rolph was not willing to accept this answer. On the other hand, however, he was also not satisfied with the “struggle for existence” as a solution of the problem. If a living being fights only for the satisfaction of its necessary needs, it will, to be sure, overpower its weaker competitors, but it will itself remain what it is. If one does not want to attribute a mysterious, mystical tendency toward perfection to this being, one must seek the cause of this perfection in external, natural circumstances. Rolph tries to give an explanation by stating that, whenever possible, every being satisfies its needs to a greater extent than is necessary.
