Samuel Butler on Duty and Inclination
By and by a subtle, indefinable malaise began to take possession of him. I once saw a very young foal trying to eat some most objectionable refuse, and unable to make up its mind whether it was good or no. Clearly it wanted to be told. If its mother had seen what it was doing she would have set it right in a moment, and as soon as ever it had been told that what it was eating was filth, the foal would have recognised it and never have wanted to be told again; but the foal could not settle the matter for itself, or make up its mind whether it liked what it was trying to eat or no, without assistance from without. I suppose it would have come to do so by and by, but it was wasting time and trouble, which a single look from its mother would have saved, just as wort will in time ferment of itself, but will ferment much more quickly if a little yeast be added to it. In the matter of knowing what gives us pleasure we are all like wort, and if unaided from without can only ferment slowly and toilsomely.
My unhappy hero about this time was very much like the foal, or rather he felt much what the foal would have felt if its mother and all the other grown-up horses in the field had vowed that what it was eating was the most excellent and nutritious food to be found anywhere. He was so anxious to do what was right, and so ready to believe that every one knew better than himself, that he never ventured to admit to himself that he might be all the while on a hopelessly wrong tack. It did not occur to him that there might be a blunder anywhere, much less did it occur to him to try and find out where the blunder was. Nevertheless he became daily more full of malaise, and daily, only he knew it not, more ripe for an explosion should a spark fall upon him.
