87. Paul Nikolaus Cossmann - Elements of Empirical Teleology

Stuttgart 1899

This book is one of the literary phenomena that are unfortunately not at all rare in our time, whose authors bear a large part of the blame for the regrettable fact that philosophy is becoming increasingly discredited. A self-evident truth, which no reasonable person doubts, is dealt with in 129 pages of comfortable breadth. What is before everyone's eyes is clothed in the most abstract formulas, and the author has the misfortune of losing his footing in the world of his abstractions and not even suspecting that his "formulations" say nothing at all. He wants to show that in nature, in which everything is connected according to cause and effect, there are also phenomena that are connected in other ways. Cause and effect form a two-part connection. Coßmann seeks to demonstrate tripartite connections within the world of life. The retinal image of the eye arises as the effect of a light stimulus on the eye-gifted organism. We have a two-part connection. The light stimulus acts on the organism and the eyelid is closed to protect against the stimulus. We have a tripartite connection, a connection between the cause - the light stimulus - the effect - the closing of the eyelid - and the purpose, the protection of the organ. Bipartite connections should be called causal, tripartite teleological purposeful. The natural science of the present is reproached for wanting to explain everything from the connections between causes and effects; and the natural science of the future is dreamed of bringing teleology to bear in all its glory. What Mr. Coßmann broadly expounds on his 129 pages can be found in the following eight lines of the book "Die Welträtsel" by Ernst Haeckel, whom our author certainly counts among those who overlook teleological connections: "In the body structure and in the life activity of all organisms we are undeniably confronted with purposeful activity. Every plant and every animal, in its composition of individual parts, appears to be just as equipped for a certain purpose in life as the artificial machines invented and constructed by man, and as long as their life continues, the function of the individual organs is just as directed towards certain purposes as the work in the individual parts of the machine." Coßmann does nothing more than put this undeniable fact into unspeakably pedantic formulas. There is no need to object to such philosophical gimmickry. It should be dealt with by those who find nothing more sensible to do in the world. But if Mr. Coßmann believes that organic natural science should incorporate teleology, he must be told that he does not understand the relationship of modern natural science to teleology. A locomotive is undoubtedly purpose-built, and Mr. Coßmann could attribute its effectiveness to his neat tripartite formula. However, the person who is to build the locomotive is not served by describing its purpose to him in a pure way. He must know the causes by which the purpose is achieved. This is how the naturalist feels about nature. He determines the purposes; but he then seeks to explain the purposeful effects from the causes. As little as a machine can be built according to its purpose, so little can a living being be explained from its purposeful arrangement.

But Mr. Coßmann faces an even more serious reproach. The purpose occurs in the time sequence after the cause. If we now disregard time and merely consider that there is a necessary connection between cause and effect, then we can also derive each cause from its effect just as well as, conversely, the effect from the cause. In a formula of mechanics that derives an effect from the cause, we only need to insert the time with a negative sign, then we have the possibility of deriving the earlier from the later. If the later then appears as a purpose, the causal connection becomes a purposeful one, and Mr. Coßmann's tripartite formula is not needed. Mr. Coßmann would now have a task if he really wanted to prove something. He would have to show that a fact valid within mechanics also corresponds to such a fact in the teleological field. For mechanics, this fact is that we can imagine a process regressing in our thoughts (through the negative sign before time), but that in reality this process cannot take place regressively. In teleology it would have to be shown that the retroactive effect of the purpose which we can imagine is really present. Mr. Coßmann is probably wary of this, because he would then have to come to the only way out that exists for the purpose theorist, to the statement of "wisdom and reason", which have first ordered the organisms as we imagine them afterwards. "Whether there are special final causes, causae finales, apart from, in addition to, beyond the causas efficientibus (forces of nature), which continue to work with blind, unintentional necessity, is a matter of scholastic dispute, and scholastic dispute is possible; but that there is in Natura naturata a purposefulness independent of man, infinitely superior to all his art, is not," says Otto Liebmann in "Gedanken und Tatsachen" (1st ed., 91). Coßmann contributed nothing, absolutely nothing, to the decision on the former; we did not need him to establish the latter. We have before us the work of a dilettante who has acquired the airs and graces of a philosopher.
