Mushroom-celebrity is the result of puzzle-headedness. A man hardly can rise to very sudden popularity without being (along with some cleverness), somewhat puzzle-headed. For the way to rise to rapid celebrity is to be a plausible advocate of prevailing doctrines; and especially to defend, with some eloquence and novelty, something which men like to believe, but have no good reason for believing. And this a skillful dissembler will never do so well as one who is himself the dupe of his own fallacies, and brings them forward, therefore, with an air of simple earnestness which implies his being, with whatever ingenuity and eloquence, puzzle-headed. A very clear-headed man must always perceive some of the truths which are generally overlooked, and must have detected some of the popular fallacies; in short, he must be somewhat in advance of the οἱ πολλοί of his contemporaries: and if he has the courage to speak his mind fairly, he must wait till the next generation, at least, for his popularity.
