“no one can mark the exact moment at which friendship becomes love.”

“Friendship is born at that moment when one person says to another: "What! You too?”

“Friendship ... is born at the moment when one man says to another "What! You too? I thought that no one but myself . . .”

“Those who cannot conceive Friendship as a substantive love but only as a disguise or elaboration of Eros betray the fact that they have never had a Friend. The rest of us know that though we can have erotic love and friendship for the same person yet in some ways nothing is less like a Friendship than a love-affair. Lovers are always talking to one another about their love; Friends hardly ever about their Friendship. Lovers are normally face to face, absorbed in each other; Friends, side by side, absorbed in some common interest. Above all, Eros (while it lasts) is necessarily between two only. But two, far from being the necessary number for Friendship, is not even the best. And the reason for this is important.... In each of my friends there is something that only some other friend can fully bring out. By myself I am not large enough to call the whole man into activity; I want other lights than my own to show all his facets... Hence true Friendship is the least jealous of loves. Two friends delight to be joined by a third, and three by a fourth, if only the newcomer is qualified to become a real friend. They can then say, as the blessed souls say in Dante, 'Here comes one who will augment our loves.' For in this love 'to divide is not to take away.”

“The mark of Friendship is not that help will be given when the pinch comes (of course it will) but that, having been given, it makes no difference at all.”

“Friendship arises out of mere Companionship when two or more of the companions discover that they have in common some insight or interest or even taste which the others do not share and which, till that moment, each believed to be his own unique treasure (or burden). The typical expression of opening Friendship would be something like, "What? You too? I thought I was the only one." ... It is when two such persons discover one another, when, whether with immense difficulties and semi-articulate fumblings or with what would seem to us amazing and elliptical speed, they share their vision - it is then that Friendship is born. And instantly they stand together in an immense solitude.”

“We may give our human loves the unconditional allegiance which we owe only to God. They they become gods: then they become demons. Then they will destroy us, and also destroy themselves. For natural loves that are allowed to become gods do not remain loves. They are still called so, but can become in fact complicated forms of hatred.”
