To this Scotus opposed an indeterminism of the extremest type, describing the will as the possibility of determining itself motivelessly in either of two opposite senses.
It is opposed to the various doctrines of FreeWill, known as voluntarism, libertarianism, indeterminism, and is from the ethical standpoint more or less akin to necessitarianism and fatalism.
It is the extreme antithesis of Indeterminism or Indifferentism, the doctrine that a man is absolutely free to choose between alternative courses (the liberum arbitrium indiferentiae).
In ethics the term is used, like indeterminism, to denote the theory that mental change cannot always be ascribed to previously ascertained psychological states, and that volition is not causally related to the motives involved.
It is true that a consistent advocate of indeterminism must deny that the will is determined by motives, and must admit that no reason can finally be given for the individual's choice beyond the act of choice itself.
Even in Clarke's system, where Indeterminism is no doubt a cardinal notion, its importance is metaphysical It may be observed that in the view of Kant and others (2) and (3) are somewhat confusingly blended.
Such aspects as concern ethics include, for example, the limited indeterminism involved in the theory, the attitude of the religious consciousness expressed by William James (Will to Believe and Pragmatism), and the pragmatic conception of the good.
