Causal body

“ This amounts to no more than saying that in the body we have instances of two things, both enduring for some time, which have a relation of mutual causal dependence on one another—a relation of ‘reciprocity.’ Frequently no more than this is meant by saying that the parts of the body form an ‘organic unity,’ or that they are mutually means and ends to one another. ”

“ For the present, however, accepting the notion of causal dependence without criticism, I wish to urge that the dependence in question is rather upon our bodies than upon our minds. The visual appearance of an object is altered if we shut one eye, or squint, or look previously at something dazzling; but all these are bodily acts, and the alterations which they effect are to be explained by physiology and optics, not by psychology. ”

“ The conclusion as to what did produce any particular sensation is plainly enough a judgment, and since it is a judgment determining the cause of the sensation, it may well be termed a causal judgment.
Causal judgments, taken by themselves, [Pg 11] are necessarily very indefinite. They do not go much beyond deciding that each individual sensation has a cause, and is not the result of chance on the one hand nor of spontaneous brain excitement on the other. Taken by themselves, causal judgments are disconnected and all but meaningless. ”

“ To me it seems a self-evident proposition that nothing whatsoever can differentiate one body of men from another, except the physical conditions in which they are set, - including, of course, under the term physical conditions the relations of place and time in which they stand with regard to other bodies of men. To suppose otherwise is to deny the primordial law of causation. To imagine that the mind can differentiate itself is to imagine that it can be differentiated without a cause. ”

“ Here then is a necessary priority in an idea, and yet true causality is not attributed to the object.
92. There is a fact in the history of philosophy which proves with the greatest evidence the truth of what I have just said. This fact is the system of occasional causes maintained by eminent philosophers. If a body, they say, strike another body at rest, it will communicate to it its motion; but this communication does not imply a true causality, but that the motion of the impinging body is a mere occasion of the motion of the body impinged. ”

“ The relation of cause and effect is a relation or condition under which events are apprehended, which relation is not given by observation, but supplied by the mind itself. According to the views which explain our apprehension of cause by reference to habit, or to a supposed law of our mental nature, causal connexion is a consequence of agencies which the mind passively obeys ”

“ And this bodily nature must last as long as those things which require it as a covering: for there will be always rational natures which need a bodily covering; and there will therefore always be a bodily nature whose coverings must necessarily be used by rational creatures, unless some one be able to demonstrate by arguments that a rational nature can live without a body. But how difficult—nay, how almost impossible—this is for our understanding, we have shown in the preceding pages, in our discussion of the individual topics. ”

“ But the truth is that no mere psychical sequence is a fact, or in any way exists. With each of its members is conjoined always a physical event, and these physical events enter into every link of causation. The state of mind, or body, is here never more than part-cause, or again more than part-effect. We may attend to either of the sides, which for our purpose is prominent; we may ignore the action of the other side, where it is constant and regular ”

“ But bodies, being most composite, are most remote from the first active cause, which is most simple. Therefore no bodies are active.
Obj. 5: Further, if a body is an agent, the term of its action is either a substantial, or an accidental form. But it is not a substantial form; for it is not possible to find in a body any principle of action, save an active quality, which is an accident; and an accident cannot be the cause of a substantial form, since the cause is always more excellent than the effect. ”

“ And at the same time this action is, more and more, seen to be limited and variously occasioned by the physical organism, and to be accompanied or followed, in a determinist fashion, by certain changes in that organism. Yet if we have now immeasurably more knowledge than men had, even fifty years ago, of this latter ceaselessly active, limiting, occasioning influence of the body upon the mind, we have also immeasurably more precise and numerous facts and knowledge in testimony of the all but boundless effect of mind over body. ”

“ What we have said so far is that there have been hitherto certain observed causal laws, and that all the empirical evidence we possess is compatible with the view that everything, both mental and physical, so far as our observation has extended, has happened in accordance with causal laws. ”

“ The human diseases are discovered by the agent, mesmerically seeing (until the organ-power is given up, or a new vocabulary established, I use the word) the internal structure of the body, and that in all its most intricate parts; the thoughts of persons, or patients, by as intricate a knowledge of their minds, propensities, and dispositions—and hero I purposely exclude from the argument the knowledge of future events. The assumption amounts to a kind of identity; the mesmeriser becomes another, and yet retains himself—at least he partakes of the person with whom he is in rapport. ”

“ It is the causation of images that is the vital problem. We have seen that they are subject to mnenic causation, and that mnenic causation may be reducible to ordinary physical causation in nervous tissue. This is the question upon which our attitude must turn towards what may be called materialism. One sense of materialism is the view that all mental phenomena are causally dependent upon physical phenomena in the above-defined sense of causal dependence. ”

“ We are here treating of efficient cause, of that which gives being to the thing, and it would often be absurd to attribute this kind of causality to conditions which on the other side are necessarily connected with the conditioned. Take away the pillar on which a body rests, and the body will fall ”

“ If the two sorts of causal laws could be sharply distinguished, we could call an occurrence "physical" when it obeys causal laws appropriate to the physical world, and "mental" when it obeys causal laws appropriate to the mental world. Since the mental world and the physical world interact, there would be a boundary between the two: there would be events which would have physical causes and mental effects, while there would be others which would have mental causes and physical effects. Those that have physical causes and mental effects we should define as "sensations." ”

“ Wherever mental action is involved, there is a special difficulty in applying the physical notion of causation. For if a Cause be conceived of as matter in motion, a thought, or feeling, or volition can be neither cause nor effect. And since mental action is involved in all social affairs, and in the life of all men and animals, it may seem impossible to interpret social or vital changes according to laws of causation. Still, animals and men are moving bodies ”

“ According to the theory in question, Mind, or, to speak more precisely, Will, is the only cause of phenomena. The type of Causation, as well as the exclusive source from which we derive the idea, is our own voluntary agency. Here, and here only (it is said) we have direct evidence of causation. We know that we can move our bodies. Respecting the phenomena of inanimate nature, we have no other direct knowledge than that of antecedence and sequence. But in the case of our voluntary actions, it is affirmed that we are conscious of power, before we have experience of results. ”

“ If you look closer you soon see, however, as to our belief in causation, that somehow or other it helps us more clearly to grasp the internal sense, the observed inner significance, of some of our conscious states, to observe what we call their causal connections. ”

“ If chance be taken in the sense of utter absence of all causal connections in the phenomena of matter and mind,—we oppose to this notion the fact that the causal judgment is formed in accordance with a fundamental and necessary law of human thought, and that no science or knowledge is possible without the assumption of its validity. ”

“ They are in principle attempts to get rid of all transeunt causality, and have been discussed in their general bearings in our chapter on the Causal Postulate, where we satisfied ourselves that any science which recognises, as Psychology has to do, the existence of finite things must also admit the principle of transeunt causality, at any rate as a working hypothesis. ”

“ The conditions of every causation are multifarious as we look at them in a regressus of causes or a progressus of effects, and as the mind of the individual can make but one judgment at a time, it may be that the one of the causes or effects which is considered, is in fact a trivial element in the causation, for in all our language we are accustomed to speak of one of the causes as the special cause, for it must be the special one in consideration. ”

“ Like the different appearances of the table to a number of simultaneous observers, the different particulars that belong to one physical object are to be collected together by continuity and inherent laws of correlation, not by their supposed causal connection with an unknown assumed existent called a piece of matter, which would be a mere unnecessary metaphysical thing in itself. ”

“ Hence arises a fundamental law of mixed natures, which, being reduced to its primary divisions, runs thus: the activities of the body correspond to the activities of the mind; that is, any overstraining of a mental activity is necessarily followed by an overstraining of certain bodily actions,—just as the equilibrium, or harmonious action, of the mental powers is associated with that of the bodily powers in perfect accord. ”

“ I conceive it to be necessary, when the hypothesis relates to causation, that the supposed cause should not only be a real phenomenon, something actually existing in nature, but should be already known to exercise, or at least to be capable of exercising, an influence of some sort over the effect. ”

“ There is a connexion between the mind and the body so subtle that it has hitherto eluded the eagle-eye of Physiology, and will perhaps remain inscrutible forever to human comprehension. But that this connexion exists is fully demonstrated by medical experience, and observation. Many bodily disorders derange the mind, and have in many instances totally destroyed it. ”

“ Causality in its mere mechanical relations may be considered for convenience, and translated as, ‘mechanical law:’ contemplated in its relation to a living organism, we may render it by such an expression as a ‘law of life’. But carry causality to its spring, trace it back to consciousness and thought, and it admits of no disguise; it is power, it is volition ”

“ Let us then assume that such a causality of life through its immediate being is checked: what will then arise in the checked life? That causality, in so far as it is in the life, can surely not be annihilated itself; only its manifestation can be checked; that causality or determined activity and freedom remains in the life, but in a manner as a causality which has no causality. ”

“ But whatever may be the arbitrary division or arrangement which we may form either of our sensations themselves, or of the organs that are previously affected, the susceptibility of the mind, by which it is capable of being affected by the changes of state in our mere bodily organs, must be regarded as, in every sense of the word, of primary value in our mental constitution. ”

“ This constancy of relations is revealed with more certainty and distinctness by every step in the progress of medical knowledge. The specialist in mental disease inquires with reason how we can acknowledge the physical processes of the body to be governed by natural law, yet assert the emancipation from law of the psychical processes which vary concomitantly with these in a manner that science shows to be perfectly constant. ”

“ Now the proximate end of the human body is the rational soul and its operations; since matter is for the sake of the form, and instruments are for the action of the agent. I say, therefore, that God fashioned the human body in that disposition which was best, as most suited to such a form and to such operations. If defect exists in the disposition of the human body, it is well to observe that such defect arises as a necessary result of the matter, from the conditions required in the body, in order to make it suitably proportioned to the soul and its operations. ”

“ If consciousness were a mere "epiphenomenon," having no "use" to the organism, it would soon perish (if it ever appeared) according to the law which says that all useless functions perish. But we know that, as a matter of fact, consciousness has grown more and more complex, as evolution has progressed.
4. The Law of Causation is doubtless valid and universal; but to assume that this is invariably physical begs the question at issue. May there not be psychical causation? Only thorough-going materialism can say "No" to this question; but materialism is today out of date. ”

“ But give to the human mind the principle of causality, admit that every sensation, as well as every phenomenon, every change, every event, has a cause, as evidently we are not the cause of certain sensations, and that especially these sensations must have a cause, and we are naturally led to recognize for those sensations causes different from ourselves, and that is the first notion of an exterior world. ”
