The concept of "mental health" in our society is defined largely by the extent to which an individual behaves in accord with the needs of the system and does so without showing signs of stress.
It is obvious that [leftists] are not cool-headed logicians systematically analyzing the foundations of knowledge. They are deeply involved emotionally in their attack on truth and reality.
Let's stick to the practical and the concrete: Would you like it if people lived in a virtual world? If machines were smarter than people? If, in the future, people, animals and plants were products of technology? If you don't like these ideas, then for you the computer and biological sciences clearly are dangerous.
The industrial-technological system may survive or it may break down. If it survives, it MAY eventually achieve a low level of physical and psychological suffering, but only after passing through a long and very painful period of adjustment and only at the cost of permanently reducing human beings and many other living organisms to engineered products and mere cogs in the social machine.
Some people have low susceptibility to advertising and marketing techniques. These are the people who aren't interested in money. Material acquisition does not serve their need for the power process.
Power depends ultimately on physical force. By teaching people that violence is wrong (except, of course, when the system itself uses violence via the police or the military), the system maintains its monopoly on physical force and thus keeps all power in its own hands.
If the system breaks down the consequences will still be very painful. But the bigger the system grows the more disastrous the results of its breakdown will be, so if it is to break down it had best break down sooner rather than later.
People do not consciously and rationally choose the form of their society. Societies develop through processes of social evolution that are not under rational human control.
The techno-industrial system is exceptionally tough due to its so-called "democratic" structure and its resulting flexibility. Because dictatorial systems tend to be rigid, social tensions and resistance can be built up in them to the point where they damage and weaken the system and may lead to revolution. But in a "democratic" system, when social tension and resistance build up dangerously the system backs off enough, it compromises enough, to bring the tensions down to a safe level.
Never lose hope, be persistent and stubborn and never give up. There are many instances in history where apparent losers suddenly turn out to be winners unexpectedly, so you should never conclude all hope is lost.
To those who think that all this sounds like science fiction, we point out that yesterday's science fiction is today's fact. The Industrial Revolution has radically altered man's environment and way of life, and it is only to be expected that as technology is increasingly applied to the human body and mind, man himself will be altered as radically as his environment and way of life have been.
