Great men are never sufficiently shown but in struggles. [ Burke ]

Genius is always sufficiently the enemy of genius by over-influence. [ Ralph Waldo Emerson ]

Sufficiently provided from within, he has need of little from without. [ Johann Wolfgang von Goethe of the poet ]

Artists may produce excellent designs, but they will avail little, unless the taste of the public is sufficiently cultivated to appreciate them. [ George C. Mason ]

Brevity is the body and soul of wit. It is wit itself, for it alone isolates sufficiently for contrasts; because redundancy or diffuseness produces no distinctions. [ Jean Paul Richter ]

Truth, in the great practical concerns of life, is so much a question of the reconciling and combining of opposites, that very few have minds sufficiently capacious and impartial to make the adjustment with an approach to correctness. [ J. S. Mill ]

The enthusiast has been compared to a man walking in a fog; everything immediately around him, or in contact with him, appears sufficiently clear and luminous; but beyond the little circle of which he himself is the centre, all is mist and error and confusion. [ Colton ]

I respect the man who knows distinctly what he wishes. The greater part of all the mischief in the world arises from the fact that men do not sufficiently understand their own aims. They have undertaken to build a tower, and spend no more labor on the foundation than would be necessary to erect a hut. [ Goethe ]
