We are bound by certain limitations of the body and mind. Those limitations where define us as what we are, what we can do and cannot do, also determine what we like or dislike, what we find satisfying and pleasing and vice versa.
We find it quite pleasurable to see the right amount of tea or coffee being poured into a pot, to see the pot filled up to a good measure without out the brew flowing over the brim. We find it quite satisfyingly pleasurably when we take in the right amount of food and drink, entertainment or rest; indulgence we know, however pleasurable for a time, always lead to physical or mental discomfort. Then, we build houses that are suitably spacious, and the neighbourhoods that are adequately sparsed. We keep our distances while driving while working around other people and while passing by each other. We find pleasurable all that comes to us in a good measure and for a right length of time.
The physical mechanism that produces pleasure is the same with which we sense pain. The fact is the pain is some pleasure that has gone out of control, either by being too intense or lasting for too long. A pleasure that will not pass out will become a horrible pain. Whereas, even an occasional sensation of slight pain lasting a short while can be quite pleasant.
The best a pleasure machine with an ON/OFF would do it will become an addiction, like a drug, like smoking, binge eating or drinking. Once hooked, to a pleasure machine we will not any point in doing anything else. You see, in life, we already have our pleasure machines, that keep us hooked, or shall we say, keep us going. The fact please is an integral part of the reward system of natural living.
We enjoy food, the taste the flavour, but neither the taste nor flavour is what our body really needs. The body needs nutrition, that it gets by bribing us with pleasure, so we may eat. How many people, and for how long, would you say, would like to engage in sex, if it were not for the pleasure that comes with it. Without natural pleasure integrated into every action we perform, and without barriers of pains surrounding the liveliest and the natural, meaningful existence will become impossible, relations will break down and life will grind to a full stop!!
