A Treatise on Toleration and Other Essays by Voltaire
My rating: 5 of 5 stars

This collection gathers together eight essays and a poem. The theme that interconnects these works is a petition to avoid petty tribalism and irrationality / superstition in the practice of one’s religion. The titular essay, “On Toleration,” sets the collection’s tone, beginning with its detailing of the murder of Jean Calas on religious grounds and its exploration of many more acts of savagery attributable to sectarian forces in alliance with authoritarian governments. The poem, “Poem on the Lisbon Disaster,” echoes the central idea of “Candide” — i.e. the idea that we live in the best of all possible worlds is patently false.

As one would expect of Voltaire, there is plenty of humor and satire throughout these pieces. The arguments are also generally well supported by facts. It is clear that Voltaire possessed a great deal of the knowledge of his day. That said, the reader may well find some factual errors. Most notably, Voltaire tends to attribute a kind of enlightened utopian vision to cultures with which he was likely largely unfamiliar as he builds a case against many within the culture with which he is familiar. This isn’t to say that there isn’t some truth to Eastern traditions being historically more tolerant of other sects than the Abrahamic religions, but the degree to which he extends these idyllic views of those outside of Europe (and the details, thereof) don’t always seem to comport with the historic record.

While some may be inclined to dismiss this book as a collection of anti-religion writings, it is really not anti-belief at all. (Though he does poke holes in many a Biblical myth, so too does he actually provide a deist argument in favor of the existence of a god or gods in the book’s final essay.) Instead, the collection is anti-intolerance, anti-superstition, and anti-authoritarianism. I’d highly recommend this book for all readers. Whatever flaws it may contain are outweighed by the great importance of its message and the cleverness with which Voltaire conveys said message.
