The passion appears to every body, but the man who feels it, entirely disproportioned to the value of the object; and love, though it is pardoned in a certain age because we know it is natural, is always laughed at, because we cannot enter into it.

Context

“But if he is in love, though we may think his passion just as reasonable as any of the kind, yet we never think ourselves bound to conceive a passion of the same kind, and for the same person for whom he has conceived it. The passion appears to every body, but the man who feels it, entirely disproportioned to the value of the object; and love, though it is pardoned in a certain age because we know it is natural, is always laughed at, because we cannot enter into it. All serious and strong expressions of it appear ridiculous to a third person; and though a lover may be good company to his mistress, he is so to nobody else. He himself is sensible of this; and as long as he continues in his sober senses, endeavours to treat his own passion with raillery5 and ridicule.” source
