“The joy of learning is as indispensable in study as breathing is to running.”

“True definition of science: the study of the beauty of the world.”

“One can never really give a proof of the reality of anything; reality is not something open to proof, it is something established. It is established just because proof is not enough. It is this characteristic of language, at once indispensable and inadequate, which shows the reality of the external world. Most people hardly ever realize this, because it is rare that the very same man thinks and puts his thought into action.”

“Love of God is pure when joy and suffering inspire an equal degree of gratitude.”

“The national interest cannot be defined as a common interest of the industrial, commercial, and financial companies of a country, because there is no such common interest; nor can it be defined as the life, liberty, and well-being of the citizens, because they are continually being adjured to sacrifice their well-being, their liberty, and their lives to the national interest. In the end a study of modern history leads to the conclusion that the national interest of every State consists in its capacity to make war.”

“The comparison of religions is only possible, in some measure, through the miraculous virtue of sympathy. We can know men to a certain extent if at the same time as we observe them from the outside we manage by sympathy to transport our own soul into theirs for a time. In the same way the study of different religions does not lead to a real knowledge of them unless we transport ourselves for a time by faith to the very center of whichever one we are studying...This scarcely ever happens, for some have no faith, and the others have faith exclusively in one religion and only bestow upon the others the sort of attention we give to strangely shaped shells. There are others again who think they are capable of impartiality because they have only a vague religiosity which they can turn indifferently in any direction, whereas, on the contrary, we must have given all our attention, all our faith, all our love to a particular religion in order to think of any other religion with the high degree of attention, faith, and love that is proper to it.”

“The man who has known pure joy, if only for a moment ... is the only man for whom affliction is something devastating. At the same time he is the only man who has not deserved the punishment. But, after all, for him it is no punishment; it is God holding his hand and pressing rather hard. For, if he remains constant, what he will discover buried deep under the sound of his own lamentations is the pearl of the silence of God.”
