Michel de Montaigne,
The Essays of Montaigne — Chapter XXVII. Of friendship…
(1877)
“ Common friendships will admit of division; one may love the beauty of this person, the good-humour of that, the liberality of a third, the paternal affection of a fourth, the fraternal love of a fifth, and so of the rest: but this friendship that possesses the whole soul, and there rules and sways with an absolute sovereignty, cannot possibly admit of a rival. ”
