[Descartes takes the stage, adjusting his cuffs with a confident flourish, his gaze penetrating and slightly amused.]

Descartes: Ah, Monsieur Hume! I shall speak plainly: I believe that free will is not merely an attribute of human nature but its very essence. Indeed, the freedom to choose defines us, separating mind from the mechanistic workings of mere matter. This faculty of volition, I would say, transcends the deterministic chain of external causes that might bind other forms of life or inert matter.

[He raises an eyebrow, considering Hume's position with a subtle smile.]

But tell me, if you contend that all human actions are driven solely by external causes, what, then, would you say animates our minds in this moment of choice?
