Socrates; he tells us that, among the Greeks, the atheistic was the philosophy most favourable to physical discoveries, and he does not hesitate to imply that the rise of the religious schools was the ruin of science.(26) Now, if we would investigate the reason of this opposition between Theology and Physics, I suppose we must first take into account Lord Bacon’s own explanation of it. It is common in judicial inquiries to caution the parties on whom the verdict depends to put out of their minds whatever they have heard out of court on the subject to which their attention is to be directed. They are to judge by the evidence; and this is a rule which holds in other investigations as far as this, that nothing of an adventitious nature ought to be introduced into the process. In like manner, from religious investigations, as such, physics must be excluded, and from physical, as such, religion; and if we mix them, we shall spoil both. The theologian, speaking of Divine Omnipotence, for the time simply ignores the laws of nature as existing restraints upon its exercise; and the physical philosopher, on the other hand, in his experiments upon natural phenomena, is simply ascertaining those laws, putting aside the question of that Omnipotence. If the theologian, in tracing the ways of Providence, were stopped with objections grounded on the impossibility of physical miracles, he would justly protest against the interruption; and were the philosopher, who was determining the motion of the heavenly bodies, to be questioned about their Final or their First Cause, he too would suffer an illogical interruption. The latter asks the cause of volcanoes, and is impatient at being told it is “the divine vengeance;” the former asks the cause of the overthrow of the guilty cities, and is preposterously referred to the volcanic action still visible in their neighbourhood. The inquiry into final causes for the moment passes over the existence of established laws; the inquiry into physical, passes over for the moment the existence of God. In other words, physical science is in a certain sense atheistic, for the very reason it is not theology.
