A very small degree of hope is sufficient to cause the birth of love

The pleasures of love are always in proportion to our fears.

Love born in the brain is more spirited, doubtless, than true love, but it has only flashes of enthusiasm; it knows itself too well, it criticizes itself incessantly; so far from banishing thought, it is itself reared only upon a structure of thought.

True love makes the thought of death frequent, easy, without terrors; it merely becomes the standard of comparison, the price one would pay for many things.

Love is like fever; it comes and goes without the will having any part of the process.

Love is like a fever which comes and goes quite independently of the will. ... there are no age limits for love.
