Part 17 (2/2)
bond between religion and science, Haeckel has shown in an impressive way in his book, Monism as a Bond between Religion and Science, Credo of a Naturalist, which appeared in 1892.
If one compares Haeckel with Hegel, one can see distinctly the difference in the tendencies of world conception in the two halves of the nineteenth century. Hegel lives completely in the idea and accepts only as much as he needs from the world of facts for the ill.u.s.tration of his idealistic world picture. Haeckel is rooted with every fiber of his being in the world of facts, and he derives from this world only those ideas toward which these facts necessarily tend. Hegel always attempts to show that all beings tend to reach their climax of evolution in the human spirit; Haeckel continuously endeavors to prove that the most complicated human activities point back to the simplest origins of existence. Hegel explains nature from the spirit; Haeckel derives the spirit from nature. We can, therefore, speak of a reversal of the thought direction in the course of the century. Within German intellectual life, Strauss, Feuerbach and others began this process of reversal. In their materialism the new direction found a provisional extreme expression, and in Haeckel's thought world it found a strictly methodical-scientific one. For this is the significant thing in Haeckel, that all his activity as a research worker is permeated by a philosophical spirit. He does not at all work toward results that for some philosophical motivation or other are considered to be the aim of his world conception or of his philosophical thinking. What is philosophical about him is his method. For him, science itself has the character of a world conception. His very way of looking at things predestines him to be a monist. He looks upon spirit and nature with equal love. For this reason he could find spirit in the simplest organism. He goes even further than that. He looks for the traces of spirit in the inorganic particles of matter:
Every atom possesses an inherent quant.i.ty of energy and in this sense is animate. Without a.s.suming a soul for the atom, the simplest and most general phenomena of chemistry are unexplainable. Pleasure and displeasure, desire and aversion, attraction and repulsion must be a common property of all material atoms. For the motion of the atoms, which must take place in the formation and dissolution of every chemical compound can only be explained if we a.s.sume that they have sensation and will. On this a.s.sumption the generally accepted chemical doctrine of affinity is really based.
As he traces spirit down to the atom so he follows the purely material mechanism of events up to the most lofty accomplishments of the spirit: The spirit and soul of man are also nothing else but energies that are inseparably bound to the material substratum of our bodies. As the motion of our flesh is bound to the form elements of our muscles, so our mind's power of thinking is bound to the form elements of our brains. Our spiritual energies are simply functions of these physical organs just as every energy is a function of a material body.
One must not confuse this mode of conception with one that dreams souls in a hazy mystical fas.h.i.+on into the ent.i.ties of nature and then a.s.sumes that they are more or less similar to that of man. Haeckel is a strict opponent of a world conception that projects qualities and activities of man into the external world. He has repeatedly expressed his condemnation of the humanization of nature, of anthropomorphism, with a clarity that cannot be misunderstood. If he attributes animation to inorganic matter, or to the simplest organisms, he means by that nothing more than the sum of energy manifestations that we observe in them. He holds strictly to the facts. Sensation and will are for him no mystical soul energies but are nothing more than.
what we observe as attraction and repulsion. He does not mean to say that attraction and repulsion are really sensation and will. What he means is that attraction and repulsion are on the lowest stage what sensation and will are on a higher one. For evolution is for him not merely an unwrapping of the higher stages of the spiritual out of the lower forms in which they are already contained in a hidden fas.h.i.+on, but a real ascent to new formations, an intensification of attraction and repulsion into sensation and will (compare prior comments in this Chapter).
This fundamental view of Haeckel agrees in a certain way with that of Goethe. He states in this connection that he had arrived at the fulfillment of his view of nature with his insight into the ”two great springs of all nature,” namely, polarity and intensification (Polaritat und Steigerung), polarity ”belonging to matter insofar as we think of it materially, intensification insofar as we think of it spiritually. The former is engaged in the everlasting process of attraction and repulsion, the latter in a continual intensification. As matter can never be and act without spirit, however, nor spirit without matter, so matter can also be intensified and the spirit will never be without attraction and repulsion.”
A thinker who believes in such a world conception is satisfied to explain by other such things and processes, the things and processes that are actually in the world. The idealistic world conceptions need, for the derivation of a thing or process, ent.i.ties that cannot be found within the realm of the factual.
Haeckel derives the form of the gastrula that occurs in the course of animal evolution from an organism that he a.s.sumes really existed at some time. An idealist would look for ideal forces under the influence of which the developing germ becomes the gastrula. Haeckel's monism draws everything he needs for the explanation of the real world from the same real world. He looks around in the world of the real in order to
recognize in which way the things and processes explain one another. His theories do not have the purpose for him, as do those of the idealist, to find a higher element in addition to the factual elements, but they merely serve to make the connection of the facts understandable. Fichte, the idealist, asked the question of man's destination. He meant by that something that cannot be completely presented in the form of the real, the factual; something that reason has to produce as an addition to the factually given existence, an element that is to make the real existence of man translucent by showing it in a higher light. Haeckel, the monistic contemplator of the world, asks for the origin of man, and he means by that the factual origin, the lower organism out of which man had developed through actual processes.
It is characteristic that Haeckel argues for the animation of the lower organisms. An idealist would have resorted to rational conclusions. He would present necessities of thought.
Haeckel refers to what he has seen.
Every naturalist, who, like me, has observed for many years the life activities of the one-celled protozoa, is positively convinced that they, too, possess a soul. This cellular soul consists also of a sum of sensations, perceptions and will activities; sensation, thinking and will of our human souls differ from those of the cellular soul only in degree.
The idealist attributes spirit to matter because he cannot accept the thought that spirit can develop from mere matter.
He believes that one would have to deny the spirit if one does not a.s.sume it to exist before its appearance in forms of existence without organs, without brains. For the monist, such thoughts are not possible. He does not speak of an existence that is not manifested externally as such. He does not attribute two kinds of properties to things: those that are real and manifested in them and those that in a hidden way are
latent in them only to be revealed at a higher stage of development. For him, there is what he observes, nothing else, and if the object of observation continues its evolution and reaches a higher stage in the course of its development, then these later forms are there only in the moment when they become visible.
How easily Haeckel's monism can be misunderstood in this direction is shown by the objections that were made by the brilliant thinker, Bartholomaeus von Carneri (1821 1909), who made lasting contributions for the construction of an ethics of this world conception. In his book, Sensations and Consciousness, Doubts Concerning Monism (1893), he remarks that the principle, ”No spirit without matter, but also no matter without spirit,” would justify our extending this question to the plant and even to the next rock we may stumble against, and to attribute spirit also to them. Without doubt such a conclusion would lead to a confusion of distinctions. It should not be overlooked that consciousness arises only through the cell activity in the cerebrum. ”The conviction that there is no spirit without matter, that is to say, that all spiritual activity is bound to a material activity, the former terminating with the latter, is based on experience, while there is no experience for the statement that there is always spirit connected with matter.” Somebody who would want to attribute animation to matter that does not show any trace of spirit would be like one who attributed the function to indicate time not to the mechanism of a watch but to the metal out of which it is made.
Properly understood, Haeckel's view is not touched by Carneri's criticism. It is safe from this criticism because Haeckel holds himself strictly within the bounds of observation. In his Riddles of the Universe, he says, ”I, myself, have never defended the theory of atom-consciousness. I have, on the contrary, expressly emphasized that I think the
elementary psychic activities of sensation and will, which are attributed to the atoms, as unconscious.” What Haeckel wants is only that one should not allow a break in the explanation of natural phenomena. He insists that one should trace back the complicated mechanism by which spirit appears in the brain, to the simple process of attraction and repulsion of matter.
Haeckel considers the discovery of the organs of thought by Paul Flechsig to be one of the most important accomplishments of modern times. Flechsig had pointed out that in the gray matter of the brain there are to be found the four seats of the central sense organs, or four ”inner spheres of sensation,” the spheres of touch, smell, sight and hearing.
”Between the sense centers lie thought centers, the 'real organs of mental life.' They are the highest organs of psychic activity that produce thought and consciousness. . . . These four thought centers, distinguished from the intermediate sense centers by a peculiar and highly elaborate nerve structure, are the true organs of thought, the only organs of our consciousness. Recently, Flechsig has proved that man has some especially complicated structures in some of these organs that cannot be found in the other mammals and that explain the superiority of human consciousness.” (Riddles of the Universe, Chapt. X.) Pa.s.sages like these show clearly enough that Haeckel does not intend to a.s.sume, like the idealistic philosophers, the spirit as implicitly contained in the lower stages of material existence in order to be able to find it again on the higher stages. What he wanted to do was to follow the simplest phenomena to the most complicated ones in his observation, in order to show how the activity of matter, which in the most primitive form is manifested in attraction and repulsion, is intensified in the higher mental operations.
Haeckel does not look for a general spiritual principle for lack of adequate general laws explaining the phenomena of nature and mind. So far as his need is concerned, his general law is indeed perfectly sufficient. The law that is manifested in the mental activities seems to him to be of the same kind as the one that is apparent in the attraction and repulsion of material particles. If he calls atoms animated, this has not the same meaning that it would have if a believer in an idealistic world conception did so. The latter would proceed from the spirit.
He would take the conceptions derived from the contemplation of the spirit down into the simplest functions of the atoms when he thinks of them as animated. He would explain thereby the natural phenomena from ent.i.ties that he had first projected into them. Haeckel proceeds from the contemplation of the simplest phenomena of nature and follows them up to the highest spiritual activities. This means that he explains the spiritual phenomena from laws that he has observed in the simplest natural phenomena.
Haeckel's world picture can take shape in a mind whose observation extends exclusively to natural processes and natural ent.i.ties. A mind of this kind will want to understand the connection within the realm of these events and beings.
His ideal would be to see what the processes and beings themselves reveal with respect to their development and interaction, and to reject rigorously everything that might be added in order to obtain an explanation of these processes and activities. For such an ideal one is to approach all nature as one would, for instance, proceed in explaining the mechanism of a watch. It is quite unnecessary to know anything about the watchmaker, about his skill and about his thoughts, if one gains an insight into the mechanical actions of its parts. In obtaining this insight one has, within certain limits, done everything that is admissible for the explanation of the operation of the watch. One ought to be clear about the fact
that the watch itself cannot be explained if another method of explanation is admitted, as, for instance, if somebody thought of some special spiritual forces that move the hour and minute hands according to the course of the sun. Every suggestion of a special life force, or of a power that works toward a ”purpose” within the organisms, appears to Haeckel as an invented force that is added to the natural processes. He is unwilling to think about the natural processes in any other way than by what they themselves disclose to observation. His thought structure is to be derived directly from nature.
In observing the evolution of world conception, this thought structure strikes us, as it were, as the counter-gift from the side of natural science to the Hegelian world conception, which accepts in its thought picture nothing from nature but wants everything to originate from the soul. If Hegel's world conception said that the self-conscious ego finds itself in the experience of pure thought, Haeckel's view of nature could reply that the thought experience is a result of the nature processes, is, indeed, their highest product. If the Hegelian world conception would not be satisfied with such a reply, Haeckel's naturalistic view could demand to be shown some inner thought experience that does not appear as if it were a mirror reflection of events outside thought life. In answer to this demand, a philosophy would have to show how thought can come to life in the soul and can really produce a world that is not merely the intellectual shadow of the external world. A thought that is merely thought, merely the product of thinking, cannot be used as an effective objection to Haeckel's view. In the comparison mentioned above, he would maintain that the watch contains nothing in itself that allows a conclusion as to the personality, etc., of the watchmaker.
Haeckel's naturalistic view tends to show that, as long as one is merely confronted with nature, one cannot make any statement concerning nature except what it records. In this
respect this naturalistic conception is significant as it appears in the course of the development of world conception. It proves that philosophy must create a field for itself that lies in the realm of spontaneous creativity of thought life beyond the thoughts that are gained from nature.
Philosophy must take the step beyond Hegel that was pointed out in a previous chapter. It cannot consist of a method that moves in the same field with natural science. Haeckel himself probably felt not the slightest need to pay any attention to such a step of philosophy. His world conception does bring thoughts to life in the soul, but only insofar as their life has been stimulated by the observation of natural processes. The world picture that thought can create when it comes to life in the soul without this stimulus represents the kind of higher world conception that would adequately complement Haeckel's picture of nature. One has to go beyond the facts that are directly contained in the watch if one wants to know, for instance, something about the form of the watchmaker's face. But, for this reason, one has no right to demand that Haeckel's naturalistic view itself should not speak as Haeckel does when he states what positive facts he has observed concerning natural processes and natural beings.
Chapter III.
The World as Illusion
Besides the current of world conception that, through the idea of evolution, wants to bring the conception of the phenomena of nature and that of the spirit into complete unity, there is another that expresses their opposition in the strongest possible form. This current also springs from natural science.
Its followers ask, ”What is our basis as we construct a world conception by means of thinking? We hear, see and touch the physical world through our senses. We then think about the facts that our senses supply concerning that world. We form our thoughts accordingly concerning the world at the testimony of the senses. But are the statements of our senses really to be trusted?”
Let us consult actual observations. The eye conveys to us the phenomena of light. We say an object sends us red light when the eye has the sensation of red. But the eye conveys sensations of light to us also in other cases. When it is pushed or pressed, or when an electric current flows through our head, the eye also has sensations of light. It is, therefore, possible that in cases in which we have the sensation of a light-sending body, something could go on in that object that has no semblance to our sensation of light. The eye, nevertheless, would transmit light to us.
The physiologist, Johannes Mueller (1801 58), drew the conclusion from these facts that what man has as his actual sensation does not depend on the external processes but on his organization. Our nerves transmit sensations to us. As we do not have the sensation of the knife that cuts us but a state of our nerves that appears to us as pain, so we also do not
