tence of which
he denies), the second traces the origin of ideas, the third deals with
language, and the fourth lays down the limits of the understanding. Other
works of his are _Thoughts concerning Education_ (1693), _On the Conduct
of the Understanding_ (_pub._ posthumously), _The Reasonableness of
Christianity_ (1695), _Treatise on Government_, and _Letters on
Toleration_. If not a very profound or original philosopher L. was a
calm, sensible, and reasonable writer, and his books were very
influential on the English thought of his day, as well as on the French
philosophy of the next century. His style is plain and clear, but lacking
in brightness and variety.

LOCKER-LAMPSON, FREDERICK (1821-1895).--Poet, _s._ of the sec. of
Greenwich Hospital, held appointments in Somerset House and the
Admiralty. He wrote a number of clever _vers de societe_, which were
_coll._ as _London Lyrics_ (1857). He also compiled _Lyra Elegantiarum_,
an anthology of similar verse by former authors, and _Patchwork_, a book
of extracts, and wrote an autobiography, _My Confidences_ (1896).

LOCKHART, JOHN GIBSON (1794-1854).--Novelist and biographer, _s._ of a

Cambusnethan, Lanarkshire, and _ed._ at Glasgow and Oxf. He studied law
at Edin., and was called to the Scottish Bar in 1816, but had little

had translated Schlegel's _Lectures on the History of Literature_), he
devoted himself more and more to a literary life. He joined John Wilson,
and became one of the leading contributors to _Blackwood's Magazine_.
After bringing out _Peter's Letters to his Kinsfolk_ (1819), sketches
mainly of Edinburgh society, he produced four novels, _Valerius_ (1821),
_Adam Blair_ (1822), _Reginald Dalton_ (1824), and _Matthew Wald_ (1824).
His _Life of Burns_ appeared in 1828. He was ed. of the _Quarterly
Review_ 1824-53. In 1820 he had _m._ Sophia, _dau._ of Sir Walter Scott,

famous _Life of Scott_, undoubtedly one of the greatest biographies in
the language. His later years were overshadowed with deep depression
caused by the death of his wife and children. A singularly reserved and
cold manner led to his being
