After first working as a clerk in Lubbock's Bank, he was appointed Assistant Secretary to the Society for the Encouragement of Art (precursor to the Royal Society of Arts), in which capacity he made many influential friends, who furnished the means for publishing his various translations, which besides Plato and Aristotle, include Proclus, Porphyry, Apuleius, Ocellus Lucanus and other Neoplatonists and Pythagoreans.
Taylor was an admirer of Hellenism, most especially in the philosophical framework furnished by Plato and the Neoplatonists Proclus and the "most divine" Iamblichus, whose works he translated into English.
Among his friends was the eccentric traveller and philosopher John "Walking" Stewart, whose gatherings Taylor was in the habit of attending.
In American editions they were read by Ralph Waldo Emerson, Bronson Alcott, and G. R. S. Mead, secretary to Helena Blavatsky of the Theosophical Society.
It appears that he and his wife were landlords at Walworth in the late 1770s to a family that included the 18-year-old Mary Wollstonecraft; it is not clear whether the future author of A Vindication of the Rights of Woman actually knew the Taylors, as at that age she left home for a job as a lady's companion.
