two propositions: _Nullum fidei Christianae
dogma, in Sacris Scripturis traditum, est rectae rationi dissentaneum_,
and _Sine actionum humanarum libertate nulla potest esse religio_.
During the same year, at the request of the author, he revised Whiston's
English translation of the _Apostolical Constitutions_.

In 1712 he published a carefully punctuated and annotated edition (folio
1712, octavo 1720) of Caesar's _Commentaries_, with elegant engravings,
dedicated to the duke of Marlborough. During the same year he published
his celebrated treatise on _The Scripture Doctrine of the Trinity_. It
is divided into three parts. The first contains a collection and
exegesis of all the texts in the New Testament relating to the doctrine
of the Trinity; in the second the doctrine is set forth at large, and
explained in particular and distinct propositions; and in the third the
principal passages in the liturgy of the Church of England relating to
the doctrine of the Trinity are considered. Whiston informs us that,
some time before the publication of this book, a message was sent to him
from Lord Godolphin "that the affairs of the public were with difficulty
then kept in the hands of those that were for liberty; that it was
therefore an unseasonable time for the publication of a book that would
make a great noise and disturbance; and that therefore they desired him
to forbear till a fitter opportunity should offer itself,"--a message
that Clarke of course entirely disregarded. The ministers were right in
their conjectures; and the work not only provoked a great number of
replies, but occasioned a formal complaint from the Lower House of
Convocation. Clarke, in reply, drew up an apologetic preface, and
afterwards gave several explanations, which satisfied the Upper House;
and, on his pledging himself that his future conduct would occasion no
trouble, the matter dropped.

In 1715 and 1716 he had a discussion with Leibnitz relative to the
principles of natural philosophy and religion, which was at length cut
short by the death of his antagonist. A collection of the papers which
passed between them was published in 1717 (cf. G. v. Leroy, _Die philos.
Probleme in dem Briefwechsel Leibniz und Clarke_, Giessen, 1893). In
1719 he was presented by Nicholas 1st Baron Lechmere, to the mastership
of Wigston's hospital in Leicester. In 1724 he published seventeen
sermons, eleven of which had not before been printed. In 1727, on the
death of
