The effect of this circumstance is, that the imagination, in running from the present impression to the absent idea, makes the transition with greater facility, and consequently conceives the object with greater force, where the connexion is common and universal, than where it is more rare and particular.

Accordingly we may observe, that the open declaration of our sentiments is called the taking off the mask, as the secret intimation of our opinions is said to be the veiling of them.

The difference betwixt an idea produced by a general connexion, and that arising from a particular one is here compared to the difference betwixt an impression and an idea.

This difference in the imagination has a suitable effect on the passions; and this effect is augmented by another circumstance.

A secret intimation of anger or contempt shews that we still have some consideration for the person, and avoid the directly abusing him.
