retroact

Retroact, rē-trō-akt′, v.i. to act backward, or in return or opposition, or on something past or preceding.—n.

The concentric is the passive state, for when one experiences a deep emotion, he must retroact.

Contemplation makes the body retroact.

Now we must retroact to see an object as a whole and not expose ourselves to error, and then, too, does not the love which a creature inspires within us naturally extend to the medium which surrounds him, and in this way does it not seem as if all that touched him partook of his life and thus acquired some title to our contemplation?

To sum up: If instinct did not lead us to retroact, to examine an object unexpectedly offered to our gaze, each surprise would expose us to error.
