“the true knowledge is disciplined and tested knowledge,—not the first thought that comes, so the true passion is disciplined and tested passion,—not the first passion that comes. The first that come are the vain, the false, the treacherous; if you yield to them they will lead you wildly and far, in vain pursuit, in hollow enthusiasm, till you have no true purpose and no true passion left. Not that any feeling possible to humanity is in itself wrong, but only wrong when undisciplined.”

English writer and art critic

John Ruskin was an English Victorian polymath, active as a writer, lecturer, art historian, art critic, draughtsman, and philanthropist. He is known for the breadth of his work and for the many fields he wrote about. His writing ranged across art and architecture, political economy, education, museology, geology, botany, ornithology, literature, history, and myth. That range made him an unusually wide-ranging public intellectual, with work that moved freely between the arts and the natural world.
