When this system has been digested, if it be thought necessary to proceed farther in the study of method, it will be proper to recommend Crousaz, Watts, Le Clerc, Wolfius, and Locke’s Essay on Human Understanding; and if there be imagined any necessity of adding the peripatetick logick, which has been, perhaps, condemned without a candid trial, it will be convenient to proceed to Sanderson, Wallis, Crackanthorp, and Aristotle.
8. To excite a curiosity after the works of God, is the chief design of the small specimen of natural history inserted in this collection; which, however, may be sufficient to put the mind in motion, and in some measure to direct its steps; but its effects may easily be improved by a philosophick master, who will every day find a thousand opportunities of turning the attention of his scholars to the contemplation of the objects that surround them, of laying open the wonderful art with which every part of the universe is formed, and the providence which governs the vegetable and animal creation. He may lay before them the Religious Philosopher, Ray, Derham’s Physico-Theology, together with the Spectacle de la Nature; and in time recommend to their perusal Rondoletius, Aldrovandus, and Linnaeus.
9. But how much soever the reason may be strengthened by logick, or the conceptions of the mind enlarged by the study of nature, it is necessary the man be not suffered to dwell upon them so long as to neglect the study of himself, the knowledge of his own station in the ranks of being, and his various relations to the innumerable multitudes which surround him, and with which his Maker has ordained him to be united for the reception and communication of happiness. To consider these aright is of the greatest importance, since from these arise duties which he cannot neglect. Ethicks, or morality, therefore, is one of the studies which ought to begin with the first glimpse of reason, and only end with life itself. Other acquisitions are merely temporary benefits, except as they contribute to illustrate the knowledge, and confirm the practice of morality and piety, which extend their influence beyond the grave, and increase our happiness through endless duration.
This great science, therefore, must be inculcated with care and assiduity, such as its importance ought to incite in reasonable minds; and for the prosecution of this design, fit opportunities are always at hand. As the importance of logick is to be shown by detecting false arguments, the excellence of morality is to be displayed by proving the deformity, the reproach, and the misery of all deviations from it. Yet it is to be remembered, that the laws of mere morality are of no coercive power; and, however they may, by conviction, of their fitness please the reasoner in the shade, when the passions stagnate without impulse, and the appetites are secluded from their objects, they will be of little force against the ardour of desire, or the vehemence of rage, amidst the pleasures and tumults of the world. To counteract the power of temptations, hope must be excited by the prospect of rewards, and fear by the expectation of punishment; and virtue may owe her panegyricks to morality, but must derive her authority from religion.
