The content of natural religion may be summed up in the following five articles, which all nations confess: 1. That there is a Supreme Being (_numen supremum_). 2. That he ought to be worshiped. 3. That virtue and piety are the chief elements of worship. 4. That man ought to repent of his sins. 5. That there are rewards and punishments in a future life. Besides these general principles, on the discovery of which Lord Herbert greatly prides himself, the positive religions contain arbitrary additions, which distinguish them from one another and which owe their origin, for the most part, to priestly deception, although the rhapsodies of the poets and the inventions of the philosophers have contributed their share. The essential principles of natural religion (God, virtue, faith, hope, love, and repentance) come more clearly to light in Christianity than in the religions of heathendom, where they are overgrown with myths and ceremonies. The _Religio Medici_ (1642) of Sir Thomas Browne shows similar tendencies. %9. Preliminary Survey.% In the line of development from the speculations of Nicolas of Cusa to the establishment of the English philosophy of nature, of religion, and of the state by Bacon, Herbert, and Hobbes, and to the physics of Galileo, modern ideas have manifested themselves with increasing clearness and freedom. Hobbes himself shows thus early the influence of Descartes's decisive step, with which the twilight gives place to the brightness of the morning. In Descartes the empiricism and sensationalism of the English is confronted by rationalism, to which the great thinkers of the Continent continue loyal. In Britain, experience, on the Continent the reason is declared to be the source of cognition; in the former, the point of departure is found in particular impressions of sense, on the latter, in general concepts and principles of the understanding; there the method of observation is inculcated and followed, here, the method of deduction. This antithesis remained decisive in the development of philosophy down to Kant, so that it has long been customary to distinguish two lines or schools, the Empirical and the Rationalistic, whose parallelism may be exhibited in the following table (when only one date is given it indicates the appearance of the philosopher's chief work): _Empiricism. Rationalism_. Bacon, 1620. (Nicolas, 1450; Bruno, 1584). Hobbes, 1651. _Descartes_, died 1650. _Locke_, 1690 (1632-1704). Spinoza, (1632-) 1677. Berkeley, 1710. _Leibnitz_, 1710. Hume, 1748. Wolff, died 1754.
