“The very condition of having Friends is that we should want something else besides Friends. Where the truthful answer to the question "Do you see the same truth?" would be "I see nothing and I don't care about the truth; I only want a Friend," no Friendship can arise - though Affection of course may. There would be nothing for the Friendship to be about; and Friendship must be about something, even if it were only an enthusiasm for dominoes or white mice. Those who have nothing can share nothing; those who are going nowhere can have no fellow-travellers.”

“For us of course the shared activity and therefore the companionship on which Friendship supervenes will not often be a bodily one like hunting or fighting. It may be a common religion, common studies, a common profession, even a common recreation. All who share it will be our companions; but one or two or three who share something more will be our Friends. In this kind of love, as Emerson said, Do you love me? means Do you see the same truth? - Or at least, "Do you care about the same truth?" The man who agrees with us that some question, little regarded by others, is of great importance can be our Friend. He need not agree with us about the answer.”

“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.”

“How could sincerity be a condition of friendship? A liking for the truth at all costs is a passion that spares nothing and that nothing can withstand.”

“When the two people who thus discover that they are on the same secret road are of different sexes, the friendship which arises between them will very easily pass – may pass in the first half hour – into erotic love. Indeed, unless they are physically repulsive to each other or unless one or both already loves elsewhere, it is almost certain to do so sooner or later. And conversely, erotic love may lead to Friendship between the lovers. But this, so far from obliterating the distinction between the two loves, puts it in a clearer light. If one who was first, in the deep and full sense, your Friend, is then gradually or suddenly revealed as also your lover you will certainly not want to share the Beloved’s erotic love with any third. But you will have no jealousy at all about sharing the Friendship. Nothing so enriches an erotic love as the discovery that the Beloved can deeply, truly and spontaneously enter into Friendship with the Friends you already had; to feel that not only are we two united by erotic love but we three or four or five are all travelers on the same quest, have all a common vision.”

“There is nothing I would not do for those who I care about. I have no notion of loving people by halves, it is not my nature. I only know 100%.”
