Each depends on the capability of imagination to represent a sequence of events or experiences.

The difference between the two processes is that in anticipation the imagination setting out from the present traces the succession of experiences in their actual order, and not in the reverse order.

It would thus appear to be a more natural and easy process than recollection, and observation bears out this conclusion.

Any object present to perception which is associated with antecedents and consequents with the same degree of cohesion, calls up its consequents rather than its antecedents.

The spectacle of the rising of the sun carries the mind much more forcibly forwards to the advancing morning than backwards to the receding night.
