“One should not reproach the theorist who undertakes such a task by calling him a fantast; instead, one must allow him his fantasizing, since for him there is no other way to his goal whatsoever. Indeed, it is no planless fantasizing, but rather a search for the logically simplest possibilities and their consequences.”

Context: The theory of relativity is a beautiful example of the basic character of the modern development of theory. That is to say, the hypotheses from which one starts become ever more abstract and more remote from experience. But in return one comes closer to the preeminent goal of science, that of encompassing a maximum of empirical contents through logical deduction with a minimum of hypotheses or axioms. The intellectual path from the axioms to the empirical contents or to the testable consequences becomes, thereby, ever longer and more subtle. The theoretician is forced, ever more, to allow himself to be directed by purely mathematical, formal points of view in the search for theories, because the physical experience of the experimenter is not capable of leading us up to the regions of the highest abstraction. Tentative deduction takes the place of the predominantly inductive methods appropriate to the youthful state of science. Such a theoretical structure must be quite thoroughly elaborated in order for it to lead to consequences that can be compared with experience. It is certainly the case that here, as well, the empirical fact is the all-powerful judge. But its judgment can be handed down only on the basis of great and difficult intellectual effort that first bridges the wide space between the axioms and the testable consequences. The theorist must accomplish this Herculean task with the clear understanding that this effort may only be destined to prepare the way for a death sentence for his theory. One should not reproach the theorist who undertakes such a task by calling him a fantast; instead, one must allow him his fantasizing, since for him there is no other way to his goal whatsoever. Indeed, it is no planless fantasizing, but rather a search for the logically simplest possibilities and their consequences.

The Nemesis of Faith (1849)
Context: I will be candid. I believe God is a just God, rewarding and punishing us exactly as we act well or ill. I believe that such reward and punishment follow necessarily from His will as revealed in natural law, as well as in the Bible. I believe that as the highest justice is the highest mercy, so He is a merciful God. That the guilty should suffer the measure of penalty which their guilt has incurred, is justice. What we call mercy is not the remission of this, but rather the remission of the extremity of the sentence attached to the act, when we find something in the nature of the causes which led to the act which lightens the moral guilt of the agent. That each should have his exact due is Just — is the best for himself. That the consequence of his guilt should he transferred from him to one who is innocent (although that innocent one he himself willing to accept it), whatever else it be, is not justice. We are mocking the word when we call it such. If I am to use the word justice in any sense at all which human feeling attaches to it, then to permit such transfer is but infinitely deepening the wrong, and seconding the first fault by greater injustice. I am speaking only of the doctrine of the atonement in its human aspect, and as we are to learn anything from it of the divine nature or of human duty.

What Buddhists Believe (1993)

Uno il saluta, un altro se gl'inchina,
Altri la mano, altri gli bacia il piede:
Ognun, quanto più può, se gli avvicina,
E beato si tien chi appresso il vede,
E più chi 'l tocca; che toccar divina
E sopranatural cosa si crede.
Lo pregan tutti, e vanno al ciel le grida,
Che sia lor re, lor capitan, lor guida.
