Daily Lucretian - Tuesday November 19, 2019 (Continuation of Book Three, Daniel Brown 1743 Edition)
And since we see the mind can be made sound, and be affected by the powers of medicine, as well as a disordered body, this is a strong evidence that the mind is mortal; for whoever attempts to make any alteration in the mind, or offers to change the nature of any other thing, must either add some new parts to it, or take off some of the old, or else transpose the former order and situation; but what is immortal can have nothing added to it, or taken from it, nor will admit of any change in the order of its parts: for whatever is so altered as to leave the limits of its first nature, is no more what it was, but instantly dies. The mind, therefore, whether it be distempered, or relieved by medicine, shows (as I observed) strong symptoms of its mortality. So evidently does the true matter of fact overthrow all false reasoning, that there is no possibility to escape its force; and the contrary opinion is either way fully refuted.
