 More seems to have written both of his anti-Spinozistic tracts hurriedly, as he was preparing the Latin translations of his works for inclusion in the second and third volumes of his Opera omnia in 1679 (volume 1 had already appeared in 1675). Indeed, he told Anne Conway that he “could not forbeare” from confuting Spinoza while he was still in the process of reading him. Both of these critiques of Spinoza, were included at the end of volume two and there is little evidence that they made any impression on contemporary readers (Hutton 1984, Henry 1987). In the attack on Spinoza’s Tractatus, however, More included an attempted refutation of the claims of Francis Glisson (which More likened to Spinoza’s views) that all matter, whether animate or inanimate, is capable of perception, is appetitive, and therefore in some sense alive. This did attract critical attention.
