Protracted Quotes (2 quotes)
Genius itself has been analyzed by the shrewdest observers into a higher capacity of attention. “Genius,” says Helvetius … “is nothing but a continued attention,” (une attention suivie). “Genius,” says Buffon, “is only a protracted patience,” (une longue patience). “In the exact sciences, at least,” says Cuvier, “it is the patience of a sound intellect, when invincible, which truly constitutes genius.” And Chesterfield has also observed, that “the power of applying an attention, steady and undissipated, to a single object, is the sure mark of a superior genius.”
In Lectures on Metaphysics and Logic (1860), Vol. 1, 179.
In not a few the [opium-eating] habit has crept upon them almost unconsciously, during the medicinal use of opiates to soothe pain, to remove sleeplessness, or to arrest protracted bowel-complaint. The risk of this evil should therefore be carefully borne in mind, for life-long misery has often been caused by undue laxity in the prescribing of opiates.
In 'Clinical Lecture On The Treatment Of The Habit Of Opium-Eating', The British Medical Journal (15 Feb 1868), 1, No. 372, 137.
In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
