sometimes acted as tutor to others, and both in that capacity and for other
reasons lived long abroad. In his earlier manhood he was much in the
society of Bacon, Jonson, and the literary folk of the English capital; and
later he was equally familiar with the society (rather scientific than
literary) of Paris. In 1647 he was appointed mathematical tutor to the
Prince of Wales; but his mathematics were not his most fortunate
acquirement, and they involved him in long and acrimonious disputes with
Wallis and others--disputes, it may be said, where Hobbes was quite wrong.
The publication of his philosophical treatises, and especially of the
_Leviathan_, brought him into very bad odour, not merely on political
grounds (which, so long as the Commonwealth lasted, would not have been
surprising), but for religious reasons; and during the last years of his
life, and for long afterwards, "Hobbist" was, certainly with very little
warrant from his writings, used as a kind of polite equivalent for atheist.
He was pensioned after the Restoration, and the protection of the king and
the Earl of Devonshire kept him scatheless, if ever there was any real
danger. Hobbes, however, was a timid and very much self-centred person,
always fancying that plots were being laid against him. He died at the
great age of ninety-two.

This long life was wholly taken up with study, but did not produce a very
large amount of original composition. It is true that his collected works
fill sixteen volumes; but they are loosely printed, and much space is
occupied with diagrams, indices, and such like things, while a very large
proportion of the matter appears twice over, in Latin and in English. In
the latter case Hobbes usually wrote first in Latin, and was not always his
own translator; but it would appear that he generally revised the work,
though he neither succeeded in obliterating nor perhaps attempted to
obliterate the marks of the original vehicle. His earliest publication was
a singularly vigorous, if not always scholastically exact, translation of
Thucydides into English, which appeared in 1629. Thirteen years later he
published in Paris the _De Cive_, which was shortly followed by the
treatise on _Human Nature_ and the _De Corpore Politico_. The latter of
these was to a great extent worked up in the famous _Leviathan_, or the
_Matter, Power, and Form of a Commonwealth_, which appeared in 1651. The
important _De Corpore_, which corresponds to the _L
