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.

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.

We must not forget, indeed, the lively interchange of ideas between the
schools (especially the influence of Descartes on Hobbes, and of the latter
on Spinoza; further, of Descartes on Locke, and of the latter on Leibnitz)
which led to reci
