THE TRUE GOOD IMPLIES A COUNTERFEIT GOOD.
26. Recognition of goodness and so-called "possession" thereof consist of enjoyment of the presence of good by the being who has received from nature the faculty of sensation. How could it make a mistake about the matter? The possibility of its being deceived implies the existence of some counterfeit; in this case, the error of this being was caused by that which resembled its good; for this being withdraws from what had deceived it as soon as the Good presents itself. The existence of a particular good for each being is demonstrated by its desire and inclination. Doubtless, the inanimate being receives its good from without; but, in the animated being, the desire spontaneously starts to pursue the Good. That is why lifeless bodies are the objects of solicitude and care of living beings, while the living beings watch over themselves.
