...[T]here is no art in being intelligible if one renounces all thoroughness of insight; but also it produces a disgusting medley of compiled observations and half-reasoned principles. Shallow pates enjoy this because it can be used for everyday chat, but the sagacious find in it only confusion, and being unsatisfied and unable to help themselves, they turn away their eyes, while philosophers, who see quite well through this delusion, are little listened to when they call men off for a time from this pretended popularity in order that they might be rightfully popular after they have attained a definite insight.

In passing we should note this curious mark of our age: The only absolute allowed is the absolute insistence that there is no absolute
