Our representations of these untried experiences, as, for example, those connected with a new set of circumstances, a new social condition, a new mode of occupation, and so on, are clearly at the first far from simple processes of inference from the past.

They are put together by the aid of many fragmentary images, restored by distinct threads of association, yet by a process so rapid as to appear like an intuition.

Indeed, the anticipation of such new experiences more often resembles an instantaneous imaginative intuition than a process of conscious transition from old experiences.

In the case of these expectations, then, there would clearly seem to be room for illusion from the first.
But even supposing that the errors connected with the first formation of an expectation cannot strictly be called illusory, we may see that such simple expectation will, in certain cases, tend to grow into something quite indistinguishable from illusion.

I refer to expectations of _remote_ events which allow of frequent renewal.
