Extremes in nature equal good produce,
Extremes in man concur to general use. [ Pope ]

Praise never gives us much pleasure unless it concur with our own opinion, and extol us for those qualities in which we chiefly excel. [ Hume ]

Resentment is a union of sorrow with malignity; a combination of a passion which all endeavor to avoid with a passion which all concur to detest. [ Johnson ]

Those critics who, in modern times, have the most thoughtfully analyzed the laws of aesthetic beauty concur in maintaining that the real truthfulness of all works of imagination - sculpture, painting, written fiction - is so purely in the imagination, that the artist never seeks to represent the positive truth, but the idealized image of a truth. [ Edward Bulwer-Lytton ]
