714. As Nature, in all the situations that we can survey as a whole, always produces an antidote for every type of poison, to say nothing of the law of sensory perception, which consists exclusively of everything having its opposite – without this contrast its existence or creation would be totally impossible – this also proves it to be a fact that the aforementioned mental hunger in terrestrial mankind's mentality has its opposite, that is to say its satisfaction. To propose a denial of this can therefore be nothing other than a claim, since it can never in any situation whatsoever be based on facts but must contradict on every point that which incontestably determines the experience of life. That satisfaction exists for every longing is established as a fact owing to the circumstance that this satisfaction is identical to the very law of existence or the prerequisite for all experience of life. The fact that in daily life we can observe many forms of longing that we cannot see the satisfaction of cannot under any circumstances invalidate the above. A longing or hunger and its satisfaction together form a whole, that is to say, a point of equilibrium or balance in the release of energy. It will therefore not be possible for a hunger or longing to cease before its satisfaction, which is the point of balance of the release of the energy of hunger, has been reached. The fact that one can sometimes have the sensation that an ordinary hunger disappears without having taken any nourishment does not mean that the hunger has disappeared. On the contrary, such a sensation will be due exclusively to a temporary weakness in the sensory sensation of the hunger, a weakness that can also be found in many other sensory areas. For instance, if you stare hard and long at a point in the distance, you will also here observe that the point can sometimes become quite unclear or blurred. This does not mean that the thing has become unclear or blurred, but that our sight is being overworked and therefore lacks its normal power until our eyes have again been able to rest. A sensation of longing can also be so persistent that the senses through which it is sensed are weakened. And for a time, we have the sensation that it has ceased. But the desire or longing itself cannot possibly cease other than through satisfaction.
