We suffer at present from a very potent detrimental influence, which is excess of mental application, forgetting that nature is a strict accountant, and if you demand of her in one direction more than she is prepared to lay out, she balances the account by making a reduction elsewhere. We forget that it is not knowledge which is stored up as intellectual fat that is of value, but that which is turned into intellectual muscle. Worse still, our system is fatal to that vigour of physique needful to make intellectual training available in the struggle of life. Yet a good digestion, a bounding pulse, and high spirits are elements of happiness which no external advantages can outbalance.
Perhaps nothing will so much hasten the time when body and mind will both be adequately cared for, as a diffusion of the belief that the preservation of health is a duty. Few seem conscious that there is such a thing as physical morality. Men's habitual words and acts imply the idea that they are at liberty to treat their bodies as they please. Disorders entailed by disobedience to nature's dictates, they regard simply as grievances; not as the effects of a conduct more or less flagitious. Though the evil consequences inflicted on their dependents, and on future generations, are often as great as those caused by time, yet they do not think themselves in any degree criminal. It is true that, in the case of drunkenness, the viciousness of a bodily transgression is recognised; but none appear to infer that, if this bodily transgression is vicious, so, too, is every bodily transgression. The fact is, that all breaches of the laws of health are physical sins. When this is generally seen, then, and perhaps not till then, will the physical training of the young receive the attention which it deserves.
Principles of Biology
In 1860 Spencer commenced a connected series of philosophical works, designed to unfold in their natural order the principles of biology, psychology, sociology and morality. "Principles of Biology" was published in 1864, and aims to set forth, the general truths of biology as illustrative of, and as interpreted by the laws of evolution. It was revised in 1899.
Proximate Definition of Life
To those who accept the general doctrine of evolution, it needs scarcely to be pointed out that classifications are subjective conceptions which have no absolute demarcations in nature corresponding to them. Consequently in attempting to define anything complex we can scarcely ever avoid including more than was intended, or leaving out something that should be taken in. Thus it happens that on seeking a definition of life there is great difficulty in finding one that is neither more nor less than sufficient. As the best mode of determining the general characteristics of vitality, let us compare its two most unlike kinds and see in what they agree.
Choosing assimilation, then, for our example of bodily life, and reasoning for our example of the life known as intelligence, it is first to be observed that they are both processes of change. Without change food cannot be taken into the blood nor transformed into tissue: neither can conclusions be obtained from premises. This conspicuous manifestation of change forms the substratum of our idea of life in general. Comparison shows this change to differ from non-vital changes in being made up of successive changes. The food must undergo mastication, digestion, etc., while an argument necessitates a long chain of states of consciousness, each implying a change of the preceding state. Vital change is further made up of many simultaneous changes. Assimilation and argument both include many actions going on together. Vital changes, both visceral and cerebral, also differ from other changes in their heterogeneity; neither the simultaneous nor the serial acts of digestion or of ratiocination are at all alike. They are again distinguished by the combination subsisting among their constituent changes. The acts that make up digestion are mutually dependent; as are those which compose a train of reasoning. Once more, they differ in being characterised by definiteness. Assimilation, respiration, and circulation, are definitely interdependent. These characterisations not only mark off the vital from the non-vital, but also creatures of high vitality from those of low vitality. Hence our formula reads thus:—Life is the definite combination of heterogeneous changes, both simultaneous and successive. Not a definite combination, allowing that there may be others, but the definite combination. This, however, omits its most distinctive peculiarity.
Correspondence Between Life and Its Circumstances
We habitually distinguish between a live object and a dead one by observing whether a change in the surrounding conditions is or is not followed by some perceptible and appropriate change in the object. Adding this all-important characteristic, our conception of life becomes—the definite combination of heterogeneous changes, both simultaneous and successive, in correspondence with external coexistences and sequences. Some illustrations may serve to show the significance of this addition.
Every act of locomotion implies the expenditure of certain internal mechanical forces, adapted in amounts and directions to balance or outbalance certain external ones. The recognition of an object is impossible without a harmony between the changes constituting perception and particular properties coexisting in the environment. Escape from enemies supposes motions within the organism related in kind and rapidity to motions without it. Destruction of prey requires a particular combination of subjective actions, fitted in degree and succession to overcome a group of objective ones.
The difference of this correspondence in inanimate and animate bodies may be expressed by symbols. Let A be a change in the environment; and B some resulting change in an inorganic mass. Then A having produced B, the action ceases. But take a sufficiently organised living body, and let the change A impress on it some change C; then, while the environment A is occasioning a, in the living body, C will be occasioning c: of which a and c will show a certain concord in time, place, or intensity. And while it is in the continuous production of such concords or correspondences that life consists, it is by the continuous production of them that life is maintained.
As, in all cases, we may consider the external phenomena as simply in relation, and the internal phenomena also as simply in relation, the broadest and most complete definition of life will be:—the continuous adjustment of internal relations to external relations. It will be best, however, commonly to employ its more concrete equivalent—to consider the internal relations as "definite combinations of simultaneous and successive changes"; the external relations as "coexistences and sequences," and the connection between them as a "correspondence."
The Degree of Life Varies as the Degree of Correspondence
It is now to be remarked that the life is high in proportion as this correspondence between internal and external relations is well-fulfilled.
Each step upward must consist in adding to the previously adjusted relations which the organism exhibits some further relation, parallel to a further relation in the environment. And the greater correspondence thus established must, other things being equal, show itself both in greater complexity of life and greater length of life—a truth which will be duly realised on remembering the enormous mortality which prevails among lowly-organized creatures, and the gradual increase of longevity and diminution of fertility which is met with in ascending to creatures of higher and higher development. Those relations in the environment to which relations in the organism must correspond increase in number and intensity as the life assumes a higher form. Perfect correspondence would be perfect life.
