Whoever does not to a certain extent remain all his life a big child, but becomes a grave, sober, thoroughly composed, and reasonable man, may be a very useful and capable citizen of this world; but never a genius.

Context

“Accordingly [pg 164] he has just as little as the child that dull gravity of ordinary men, who, since they are capable only of subjective interests, always see in things mere motives for their action. Whoever does not to a certain extent remain all his life a big child, but becomes a grave, sober, thoroughly composed, and reasonable man, may be a very useful and capable citizen of this world; but never a genius. In fact, the genius is so because that predominance of the sensible system and of intellectual activity which is natural to childhood maintains itself in him in an abnormal manner through his whole life, thus here becomes perennial.” source
