Fernando Lopes

“There are many subjects upon which, if we hold an opinion at all, we should hold it tentatively, waiting for more light, and retaining a willingness to be enlightened. Many a bitter and fruitless quarrel might be avoided, if more persons found it possible to maintain this philosophical attitude of mind. Philosophy is, after all, reflection, and the reflective man must realize that he is probably as liable to error as are other men. He is not infallible, nor has the limit of human knowledge been attained in his day and generation. He who realizes this will not assume that his neighbor is always wrong, and he will come to have that wide, conscientious tolerance, which is not indifference, but which is at the farthest remove from the zeal of mere bigotry.”
― George Stuart Fullerton, An Introduction to Philosophy
