(July 17, 1674 – November 25, 1748) is recognised as the "Father of English Hymnody", as he was the first prolific and popular English hymnwriter, credited with some 750 hymns. Many of his hymns remain in active use today and have been translated into many languages.

The Whole Book of Psalms, published in 1562, went through 78 editions before 1600, and is called the Old Version. Only one psalm from it is still in common use. It is a paraphrase of Psalm 100, sung to the tune known as "Old Hundred" or "The Doxology" ("Praise God from Whom all blessings flow").

All people that on earth do dwell, Sing to the Lord with cheerful voice. Him serve with mirth; His praise forth tell. Come ye before Him and rejoice.
Besides being a great hymn-writer, Isaac Watts was also a renowned theologian and logician, writing many books on these subjects. One such text on logic was particularly popular; its full title was, Logick
The Logick was a textbook which followed the Aristotelian and scholastic traditions in logic, (for which, see the Organon, the logical works of Aristotle collected and edited by Porphyry), although the influence of Locke's Essay Concerning Human Understanding is also evident in the work. Isaac Watts' Logick became the standard text on logic at Oxford, Cambridge, Harvard and Yale; being used at Oxford for well over 100 years. Isaac Watts' writing style, his thorough acquaintance with logic as it was conceived during his time, and his personal conception of the subject, mean that the text has historical value, and remains of interest to the student of Aristotelian logic.

The Logick was followed in 1741 by a supplement, The Improvement of the Mind, which itself went through numerous editions and later inspired Michael Faraday.
