Wollaston also published anonymously a small book, On the Design of the Book of Ecclesiastes, or the Unreasonableness of Men's Restless Contention for the Present Enjoyments, represented in an English Poem (London, 1691).
Indeed, he gloried in the inherent and divine unreasonableness of Christianity, and brutally denounced reason as a cunning fool, " a pretty harlot."
He obtained letters treating of the question (since printed at the end of Stillingfleet's Unreasonableness of Separation) from Le Moyne, professor of divinity at Leiden, and the famous French Protestant divine, Jean Claude.
Then He complained of the unreasonableness of an age which refused John as too austere and Himself as too lax and as being " the friend of publicans and sinners."
But, though in 1680 he published his Unreasonableness of Separation, his willingness to serve on the ecclesiastical commission of 1689, and the interpretation he then proposed of the damnatory clauses of the Athanasian creed, are proof that to the end he leaned towards toleration.
