Adapted from An Enquiry Concerning Human Understanding by David Hume (1748)
Everyone will readily allow that there is a considerable difference between the perceptions of the mind, when a man feels the pain of excessive heat, or the pleasure of moderate warmth, and when he afterwards recalls to his memory this sensation, or anticipates it by his imagination. These faculties may mimic or copy the perceptions of the senses; but they can never entirely reach the force and vivacity of the original sentiment. The utmost we say of them, even when they operate with greatest vigour, is that they represent their object in so lively a manner that we could almost say we feel or see it: but, except the mind be disordered by disease or madness, they can never arrive at such a pitch of vivacity as to render these perceptions altogether indistinguishable. All the colours of poetry, however splendid, can never paint natural objects in such a manner as to make the description be taken for a real landscape. The most lively thought is still inferior to the dullest sensation.
We may observe a like distinction running through all the other perceptions of the mind. A man in a fit of anger is actuated in a very different manner from one who only thinks of that emotion. If you tell me that any person is in love, I easily understand your meaning and form a just conception of his situation, but never can mistake that conception for the real disorders and agitations of the passion.

What is the result of being in love?


A man's mind functions differently.

A man loses his senses.

A man's mind goes crazy.

A man counts the ways he can compare thee to a summer's day.
