(Latin: in, not; tolero, bear)
Is a want of reasoned patience and magnanimous forbearance toward those in whom we should recognize an inviolable liberty or grant a reasonable indulgence.
Intolerance toward error is not wrong any more than a physician's intolerance toward disease is wrong, for truth by its nature admits of no compromise with error.
Intolerance toward the erring, however, is wrong for the erring are personal and human to whom we are bound by all the laws of charity.
See also: tolerance.
