Excerpt from An Introductory Lecture, Delivered Before the Medical Class of the University of Maryland: September, 1840
This moment is one of interest to you, gentlemen, as well as to us. For you have now to chose whether you will take no heed to the history of the past, or whether you will profit by its warnings, - whether you will thoughtlessly follow the footsteps of those who have wandered from the right path; or whether you will not rather strive with the self denying ardour of the true votaries of science, for the rewards of fame and of fortune, that are within your reach. And you have incentives still more exalted than the prospect of attaining those, the more immediate objects of your exertions. On the tablet of creation, exposed to our w, we find written in words of light the high and sublime truth, that the human mind, an emanation from the divinity, departs from the eternal order of its nature, if it bends to ignoble influences, and obeys where it should rule. Every error to which it does homage, every prejudice and re spect for '0pinion which are suffered to stifle the free expres sion of its convictions, every passion whose voice sounds above the calm accents of wisdom, affects not only that individual mo ment of its history, but degrades it from its high position; and its progress, from that time forward, must be from a lower step in the seals of intelligence. The horizon of its ion is. Nar rowed, and it less clearly beholds in each truth, the connecting links of universal wisdom, and the grand chain of mutual sup port and dependence which pervades the universe. And if there is one consideration more than another, that should nerve us to pursue our course unfaltering, and make us shrink from every dereliction, it is the thought, that each will sink us in the scale of intellectual existences, and remove our starting point farther from our goal.
