'Is it worse to be the last to love, or the first to grow tired?'
'In the former case one's self-esteem is hurt; in the latter one's conscience.'
'The wounds of conscience are sooner cured than those of vanity.'
'Whoever loves most loves longest.'
'No, whoever is least loved loves longest.'
'How is that to be explained?'
'The contradictions of human nature will usually suffice to explain everything.'
'But there may be another explanation also; the one who is least loved is the least cloyed, and the most apprehensive of alteration.'
'Love is best worked with egotism, as gold is worked with alloy.'
'Surely the essential loveliness of love is self-sacrifice?'
