Of this one guiding fact, as a basis of judgment, we may be quite sure--viz., that whatever revolts our moral sense as earnest women, is not in accordance with steady progress; it cannot be permanently true, and no amount of clever or logical sophistry can make it true. It will be a real service that we, as medical women, may render to the profession if we search out--calmly, patiently, but resolutely--why what revolts our enlightened sense of right and wrong is not true. We shall thus bring to light the profound reason why the moral faculties are antecedent or superior to the intellectual faculties, and why the sense of right and wrong must govern medical research and practice, as well as all other lines of human effort. As experience enlarges, we observe the immense separation in lines of conduct which gradually results from an initial divergence between right and wrong--a divergence almost imperceptible at first. We are thus compelled to come to the conclusion, in relation to our own profession, that the worship of the intellect, or so-called knowledge, as an end in itself, entirely regardless of the character of the means by which we seek to gain it, is the most dangerous error that science can make. This false principle, if adopted by the medical profession, will degrade it, and inevitably produce distrust and contempt in the popular mind. The second danger against which the student of medicine must guard is the materialism which seems to arise from undue absorption in the physical aspect of nature, and which spreads like a blight in our profession. The basis of materialism is the assertion that only sense is real. Our medical studies necessarily begin with minute and prolonged study of what we term ‘dead matter.’ If this study be carried on without reverence, it appears to blind the student to any reality except the material under his scalpel or in his crucible--_i.e._, the facts that the senses reveal. Proceeding logically from this false premiss, that only sense is real, mind is looked upon as an outcome of the brain, and life as the result of organization of matter, which is destroyed when the organization of the material body is broken up.
