1686 – 1748
John Balguy (1686–1748) was an English clergyman and rationalist moral philosopher who argued that moral distinctions are grounded in reason rather than sentiment or feeling. A disciple of Samuel Clarke, he opposed the moral sense theories of Shaftesbury and Hutcheson, maintaining that virtue consists in conformity to eternal rational truths. He extended similar arguments to aesthetics, holding that beauty and excellence are objective features of things rather than projections of subjective pleasure.
