Context

“and is not love itself a fancy, a falsehood, an illusion? We are far more in love with our own fancy than with the object of it. If we saw the object of our affections as it is, there would be no such thing as love. When we cease to love, the person we used to love remains unchanged, but we no longer see with the same eyes; the magic veil is drawn aside, and love disappears. But when I supply the object of imagination, I have control over comparisons, and I am able easily to prevent illusion with regard to realities. For all that I would not mislead a young man by describing a model of perfection which could never exist;” source
