From first to last, whether we consider his childish waywardness and outbreaks of violent passion, which persevered in a less childish form through manhood; or the fits of intense depression and melancholy, alternating with spells of high nerve-tension and feverish excitement; or the restlessness and impatient energy which showed themselves always and everywhere, and at times drove him like a wild man into the woods, "seeking rest and finding none;" or the prophetic, not to say, the fanatical strain which breaks out in so much of his writing, especially in the _Paroles d'un Croyant_,--in all alike there is evident that predominance of the imaginative and emotional elements which, combined with intellectual gifts, constitute genius as commonly understood. For such a character the training which would suffice for half a dozen good little Jeans would be wholly inadequate. So much fire and feeling ill submits to the yoke of self-restraint in matters moral or intellectual. The mind is apt to be fascinated by the brilliant pictures of the imagination and to become a slave to the tyranny of a fixed idea; while the strength of passionate desire paralyzes the power of free deliberation. It is precisely this self-restraint, the fruit of a careful education given and responded to, that we miss in De Lammenais both in his moral character and in his mind. Peace and tranquillity of soul are essential to successful thinking, more especially in philosophy; and in proportion as a brilliant imagination is a help, it is also a danger if let run riot. At times, wearied out with himself, he seems to have felt the need of retreat and quiet; but he was almost as constitutionally incapable of keeping still, as certain modern statesmen in their retirement from public life. We smile when we hear him in the violent first fervour of his conversion, talking about becoming a Trappist, and, later, a Jesuit. He knew himself better when he shrank so long and persistently from the yoke of priesthood, and when, having yielded against his truer instincts to the indiscreet zeal of pious friends, he experienced an agony of repugnance at his first Mass. With different antecedents he might have profited by the yoke, but as things stood it could but gall him.
