Aristotle, Nicomachean Ethics
H. Rackham, Ed.

though not in the same way as sailors are fearless, for he thinks there is no hope of safety, and to die by drowning is revolting to him,¹ whereas sailors keep up heart because of their experience. [12] Also Courage is shown in dangers where a man can defend himself by valor or die nobly, but neither is possible in disasters like shipwreck.7.

Now although the same things are not fearful to everybody, there are some terrors which we pronounce beyond human endurance, and these of course are fearful to everyone in his senses. And the terrors that man can endure differ in magnitude and degree; [2] as also do the situations inspiring confidence.² [2] But the courageous man is proof against fear so far as man may be. Hence although he will sometimes fear even terrors not beyond man's endurance, he will do so in the right way, and he will endure them as principle dictates, for the sake of what is noble³; for that is the end at which virtue aims. [3] On the other hand it is possible to fear such terrors too much, and too little; and also to fear things that are not fearful as if they were fearful. [4] Error arises either from fearing what one ought not to fear, or from fearing in the wrong manner, or at the wrong time, or the like; and similarly with regard to occasions for confidence. [5]

The courageous man then is he that endures or fears the right things and for the right purpose and in the right manner and at the right time, and who shows confidence in a similar way. （For the courageous man feels and acts as the circumstances merit, and as principle may dictate. [6] And every activity aims at the end that corresponds to the disposition of which it is the manifestation. So it is therefore with the activity of the courageous man: his courage is noble; therefore its end is nobility, for a thing is defined by its end; therefore the courageous man endures the terrors and dares the deeds that manifest courage, for the sake of that which is noble.） [7]

Of the characters that run to excess, on the other hand, he who exceeds in fearlessness has no name （this, as we remarked before,⁴ is the case with many qualities）, but we should call a man mad, or else insensitive to pain, if he feared nothing, ‘earthquake nor billows,’⁵ as they say of the Kelts; he who exceeds in confidence [in the face of fearful things⁶] is rash. [8] The rash man is generally thought to be an impostor, who pretends to courage which he does not possess; at least, he wishes to appear to feel towards fearful things as the courageous man actually does feel, and therefore he imitates him in the things in which he can.⁷ [9] Hence most rash men really are cowards at heart, for they make a bold show in situations that inspire confidence, but do not endure terrors. [10]

He that exceeds in fear⁸ is a coward, for he fears the wrong things, and in the wrong manner, and soon with the rest of the list.
