Quote by Saint Augustine of Hippo, De Lib
Will is to grace as the horse is to the rider.Bartlett's 15th edition notes This is considered the most important definition of the relation of grace to free will in the Middle Ages.
Summary
This quote draws an analogy between will and grace by comparing them to a horse and its rider. It implies that just as a horse is guided and directed by its rider, grace is the guiding force that directs and influences one's free will. In the context of the Middle Ages, this comparison holds significance as it reflects the understanding that individuals have the power to make choices (free will), but that these choices are ultimately shaped and guided by the divine intervention and influence of grace.
