It is the example of the rider who wishes to become an expert horseman: "None of your soft-mouthed, docile animals for me," he says; "the horse for me to own must show some spirit" in the belief, no doubt, if he can manage such an animal, it will be easy enough to deal with every other horse besides. And that is just my case. I wish to deal with human beings, to associate with man in general; hence my choice of wife. I know full well, if I can tolerate her spirit, I can with ease attach myself to every human being else.
If I am to live longer, perhaps I must live out my old age, seeing and hearing less, understanding worse, coming to learn with more difficulty and to be more forgetful, and growing worse than those to whom I was once superior. Indeed, life would be unliveable, even if I did not notice the change. And if I see the change, how could life not be even more wretched and unpleasant?
It is a disgrace to grow old through sheer carelessness before seeing what manner of man you may become by developing your bodily strength and beauty to their highest limit. But you cannot see that, if you are careless; for it will not come of its own accord.
