This analysis will show in the first place that the Jacobin is not a rationalist, but a believer. Far from building his belief on reason, he moulds reason to his belief, and although his speeches are steeped in rationalism he employs it very little in his thoughts and his conduct. A Jacobin who reasoned as much as he is accused of reasoning would be sometimes accessible to the voice of reason. Now, observation proves, from the time of the Revolution to our own days, that the Jacobin is never influenced by reasoning, however just, and it is precisely here that his strength resides. And why is he not accessible to reason? Simply because his vision of things, always extremely limited, does not permit of his resisting the powerful and passionate impulses which guide him. These two elements, feeble reason and strong passions, would not of themselves constitute the Jacobin mind. There is another. Passion supports convictions, but hardly ever creates them. Now, the true Jacobin has forcible convictions. What is to sustain them? Here the mystic elements whose action we have already studied come into play. The Jacobin is a mystic who has replaced the old divinities by new gods. Imbued with the power of words and formulae, he attributes to these a mysterious power. To serve these exigent divinities he does not shrink from the most violent measures. The laws voted by our modern Jacobins furnish a proof of this fact. The Jacobin mentality is found especially in narrow and passionate characters. It implies, in fact, a narrow and rigid mind, inaccessible to all criticism and to all considerations but those of faith. The mystic and affective elements which dominate the mind of the Jacobin condemn him to an extreme simplicity. Grasping only the superficial relations of things, nothing prevents him from taking for realities the chimerical images which are born of his imagination. The sequence of phenomena and their results escape him. He never raises his eyes from his dream. As we may see, it is not by the development of his logical reason that the Jacobin exceeds. He possesses very little logic of this kind, and therefore he often becomes dangerous. Where a superior man would hesitate or halt the Jacobin, who has placed his feeble reason at the service of his impulses, goes forward with certainty. So that although the Jacobin is a great reasoner, this does not mean that he is in the least guided by reason. When he imagines he is being led by reason it is really his passions and his mysticism that lead him. Like all those who are convinced and hemmed in by the walls of faith, he can never escape therefrom.
