It is most convenient to regard ``intention'' as including not only such results of volition as the agent desired to realise, but also any that, without desiring, he foresaw as certain or probable. The question how far we are responsible for all the foreseen consequences of our acts, or, in the case of acts prescribed by definite moral rules, only for their results within a certain range, will be considered when we come to examine the Intuitional Method.
