There is no real love without enthusiasm, and no enthusiasm without an object of perfection real or supposed, but always present in the imagination.

Context

“but let it consist of Roman ladies, you will all gaze with the eyes of the Volscians and feel with the heart of Coriolanus. I will go further and maintain that virtue is no less favourable to love than to other rights of nature, and that it adds as much to the power of the beloved as to that of the wife or mother. There is no real love without enthusiasm, and no enthusiasm without an object of perfection real or supposed, but always present in the imagination. What is there to kindle the hearts of lovers for whom this perfection is nothing, for whom the loved one is merely the means to sensual pleasure? Nay, not thus is the heart kindled, not thus does it abandon itself to those sublime transports which form the rapture of lovers and the charm of love.” source
