A Dissertation on Horses Wherein It is Demonstrated, by Matters of Fact, as Well as from the Principles of Philosophy, That Innate Qualities Do Not Exist, and That the Excellence of This Animal is Altogether Mechanical and Not in the Blood

This early‑mid‑18th‑century work takes a skeptical look at the prevailing belief that a horse’s greatness comes from mysterious bloodlines. The author argues, with a mix of observable facts and philosophical reasoning, that a horse’s performance is essentially the result of physical structure and training rather than inherited “innate qualities.” Along the way, he peppers his argument with vivid anecdotes about racing practices, chariot contests, and the occasional boastful stallion whose reputation rests more on patronage than on measurable merit.

Beyond the debate, the dissertation offers a rare glimpse into how English breeders of the period treated their animals, contrasted with the disciplined conformation standards that later emerged. Readers will also encounter fascinating sketches of Arab nomadic horse‑raising, mentions of the ancient Nisaean strain surviving in Turkey, and early stories of the famed Godolphin Arabian. It’s an engaging snapshot of a time when superstition still guided the sport of kings, yet reason was beginning to take the reins.
