Fully titled: The Improvement of the Mind, or a Supplement to the Art of Logic. in Two Parts. by Isaac Watts, D.D. Also His Posthumous Works, Published from His Manuscript. by D. Jennings, D.D. and P. Doddridge, D.D.
A scarce work published by J. Cuthell & J. Lackington (London, 1792). Full period mottled calf. Front hinge starting to crack (as pictured) but holding strong.
The first edition was published in 1741. Samuel Johnson writes, “Few books have been perused by me with greater pleasure than [Watts’] Improvement of the Mind, of which the radical principles may indeed be found in Locke’s Conduct of the Understanding; but they are so expanded and ramified by Watts, as to confer on him the merit of a work in the highest degree useful and pleasing. Whoever has the care of instructing others, may be charged with deficiency in his duty if this book is not recommended?” (Johnson, Life of Dr. Watts).
Duodecimo sized volume (two parts in one volume plus essays)
