XXVII—CAUSATION
Causation differs from all other categories in that one of its elements is mental. It is a series beginning in the mind—in this relation denominated cause—and developing into objective phenomena called effects or an effect. The series being known by judgment we can infer similar causes from perception of similar effects. The commonest causation is the use and interpretation of language. Because we utter words from a certain motive we infer that all who utter the same words do so from the same motive. That is the reason of the intelligibility of words.
This category is peculiar from the extremely narrow range of the experience which supplies the judgments. We never perceive any mind but one—our own—and this has to supply all the judgments by which we reason concerning other minds. There is therefore no category in which correct reasoning is so difficult and so rare. No amount of experience entirely overcomes this defect, for if we are ignorant we cannot understand the wise, and if we are wise we cannot conceive the motives of the ignorant and vicious. Only those persons who are mentally very like each other are mutually comprehensible.
This category has a further peculiarity. In all the rest the inference relates to objective experience, and this being due to interaction of minds we are justified in saying that until it is perceived it has no existence. But in causation we are inferring something with reference to a mind, and this exists though we never can perceive it. We know that minds exist without perception because we know that our own exists though no one perceives us—though we are in total darkness and silence and cannot ourselves perceive our bodies. As already stated, Existence has not the same meaning when applied to objects and to minds, objects being merely temporary conditions of minds. The non-existence of inferred but unperceived objects does not follow from any defect in the faculty of inference, but depends on the essential character of objects. They are created by mutual contact of minds and cannot exist without that condition, however clearly they may be inferred and however correctly their appearance may be predicted.
Causation is confounded with sequence because both are series. Let me illustrate the difference between them by an example. I turn the stop-cock of a pipe, and water flows from the open end of the pipe. In popular and even scientific language it would be said that I caused the water to flow. But this is incorrect. All I caused was the turning of the tap; that alone was wholly due to my energy and intelligence. There followed as a sequence the outflow of water, but that was due partly to cosmic force and partly to the previous human causation (not mine) implied in making and laying down the pipe so as to utilise the cosmic force. I merely removed an obstacle that prevented the further development of the force in a particular direction. My relation to the outflow was sequence, not causation.
In observation sequence registers fixed or probable series of objects without regard to their causes. It is sufficient if they occur regularly enough to justify prediction. Causation, on the other hand, pays no regard to physical connection of any sort, but seeks out the being or beings who supplied the energy producing an effect or series of effects. The speculations in causation pass quite beyond the domain of objectivity, over into the realm of true creation.
When we read that 'the succession of events is an endless chain of effects which are in their turn causes of new effects,' what is meant is sequence, and for 'cause' and 'effect' the terms 'antecedent' and 'consequent' should have been employed. Sequences may be 'chains' and may be long, but if so their links have been forged by independent causes acting across the chain; as when a line of soldiers fire in succession at regular intervals, or as in the case of the moon's quarters. In these instances the objects, although forming a series, has each a cause of its own.
Certainly a causation is a series, for the cause precedes the effect. But an effect is never the cause of a succeeding effect. When this appears to be the case the explanation is that the energy was not exhausted in producing the immediate simple effect, but has produced a complicated effect in which a series may be discovered. An objective effect, being a mere flash of consciousness—a shadow on a window-blind—is incapable of causing anything.
Analysis of Cause. Cause is mind in action. It consists of at least energy and a sentimental motive—energy exerted to gratify sentiment. If the mind is intellectualised there will probably be an ideal element in the cause—in this connection called plan or design—for the better direction of the energy. Normal human causation consists of an effort of mind directed towards the objective realisation of a plan, for the gratification of a sentiment. This is the same as WILL.
