If this hypothetical
man represent the ascending line of life--that is to say, if he promise all that which is highest in a Graeco-Roman sense, then it is likely that he will be condemned as wicked if introduced into the society of men representing the opposite and descending line of life.
I mean that, in attempting to state the PROXIMATE cause of the present event, some past event or events must be included, unless we take refuge in hypothetical modifications of brain structure.
It is, in fact, hypothetical, invoked for theoretical uses, and not an outcome of direct observation.
I do not wish to urge that this form of causation is ultimate, but that, in the present state of our knowledge, it affords a simplification, and enables us to state laws of behaviour in less hypothetical terms than we should otherwise have to employ.
It is quite probable that there is such a difference in the brain, but its nature is unknown and it remains hypothetical.
This law would need to be supplemented by some account of the influence of frequency, and so on; but it seems to contain the essential characteristic of mnemic phenomena, without admixture of anything hypothetical.
In the Child/Davidson pair of hypotheticals
, there is a present voluntary act ("ringing the bell") in the first hypothetical
and past voluntary acts (for example, "walking near the button") in the second.
