text: The gloom, however, furnished me with some food for thought; I felt a certain mental thrill, and a transformation unaccompanied by fear, due to the novelty and the unpleasantness of an unusual occurrence. Of course I am not speaking to you of myself at this point, because I am far from being a perfect person, or even a man of middling qualities; I refer to one over whom fortune has lost her control. Even such a man's mind will be smitten with a thrill and he will change colour. For there are certain emotions, my dear Lucilius, which no courage can avoid; nature reminds courage how perishable a thing it is. And so he will contract his brow when the prospect is forbidding, will shudder at sudden apparitions, and will become dizzy when he stands at the edge of a high precipice and looks down. This is not fear; it is a natural feeling which reason cannot rout. That is why certain brave men, most willing to shed their own blood, cannot bear to see the blood of others. Some persons collapse and faint at the sight of a freshly inflicted wound; others are affected similarly on handling or viewing an old wound which is festering. And others meet the sword-stroke more readily than they see it dealt.
