جای تعجب نيست که اسپينوزا این رساله را نوشته است، چون خود او محصول جامعه‌ای تحمل‌پذير بود: او يک يهودی پرتغالی بود که در هلند زندگی می‌کرد.
It is not surprising that Spinoza should have written this treatise, for he was himself a product of a tolerant society: he was a Portuguese Jew living in Holland.
