Prospectus of a series of lectures, or A new practical system of human reason : calculated to discharge the mind from a great mass of error, and to facilitate its labour in the approximation of moral truth, divested of all metaphysical perplexities and nullities; accommodated to the most ordinary capacities, in a simple method, which dispenses equally with the study of the college, or the lecture of musty libraries. / By John Stewart the traveller.
