David and Mary Norton present the definitive scholarly edition of one of the greatest philosophical works ever written. This first volume contains the critical text of David Hume's Treatise of Human Nature (1739/40), followed by the short Abstract (1740) in which Hume set out the key arguments of the larger work; the volume concludes with A Letter from a Gentleman to his Friend in Edinburgh (1745), Hume's defence of the Treatise when it was under attack from ministers seeking to prevent Hume's appointment as Professor of Moral Philosophy at the University of Edinburgh.

In this groundbreaking two-volume textbook first published in 1867, Lord Kelvin and Peter Guthrie Tait offer a unified scientific explanation of the physical world through the laws of energy. They defined much of what today is considered physics, covering such realms as liquid motion, instantaneous velocity, and the motion of a rigid body around a fixed point. From simple movement to fluid dynamics the authors provide readers with the necessary science and mathematics to describe complex systems of motion. Irish scientist, engineer, and author LORD WILLIAM THOMSON KELVIN (1824-1907) is considered an foundational thinker of modern physics. He invented the Kelvin temperature scale and also helped develop the first transatlantic telegraph cable. Scottish physicist PETER GUTHRIE TAIT (1831-1901) was educated at Cambridge. Among his writings is the scientific and religious text The Unseen Universe (1901).
