It is curious how many philosophers from Plato to Keynes' time have believed in and advocated the control of society by "philosopher kings". According to Plato, "its kings must be those who have shown the greatest ability in philosophy", but--realistically--he added, "and the greatest aptitude for war". Such people may exist in the imagination and occasionally someone with the necessary qualities may briefly dominate the stage of history, but it is a naive appreciation of human nature to imagine that such processed paragons can be invested with the necessary powers and not be tempted to take advantage of their situation.

It is frequently more rewarding merely to ask pertinent questions. It may get someone to go and look for an answer. If you get a silly answer, which can easily happen, you can return to the charge with even more telling effect. Whatever happens, don't give up and don't despair. Results may not be immediately apparent, but you may have touched a receptive chord without knowing it. Even the most unsympathetic and unenlightened politician, industrialist or bureaucrat begins to take notice when a lot of people write about the same subject.

For example, the World Health Organization Project, designed to eradicate malaria from Sri Lanka in the postwar years, achieved its purpose. But the problem today is that Sri Lanka must feed three times as many mouths, find three times as many jobs, provide three times the housing, energy, schools, hospitals and land for settlement in order to maintain the same standards. Little wonder the natural environment and wildlife in Sri Lanka has suffered. The fact [is] ... that the best-intentioned aid programs are at least partially responsible for the problems.
The industrial revolution sparked the scientific revolution and brought in its wake better public hygiene, better medical care and yet more efficient agriculture. The consequence was a population explosion which still continues today.
The sad fact is that, instead of the same number of people being very much better off, more than twice as many people are just as badly off as they were before. Unfortunately all this well-intentioned development has resulted in an ecological disaster of immense proportions.

The conflict between instinct and reason has reached a critical stage in man's affairs, largely because the explosion of facts has revealed the instincts for what they are and at the same time it has undermined traditional philosophies and ideologies. The explosion of facts has effectively altered mankind's physical and intellectual environment and when any environment changes, the process of natural selection is brutal and merciless. «Adapt or die» is as true today as it was in the beginning.

If the world pollution situation is not critical at the moment, it is as certain as anything can be that the situation will become increasingly intolerable within a very short time. The situation can be controlled, and even reversed; but it demands cooperation on a scale and intensity beyond anything achieved so far.
I realize that there are vital causes to be fought for, and I sympathize with people who work up a passionate concern about the all too many examples of inhumanity, injustice, and unfairness; but behind all this hangs a deadly cloud. Still largely unnoticed and unrecognized, the process of destroying our natural environment is gathering speed and momentum. If we fail to cope with the challenge, the other problems will pale into insignificance.

So long as they [birth control methods] ... remained taboo subjects the chances of making any impression on the human population explosion were that much more remote.
In the introduction to the IUCN Red Data Books which list all animals and plants under threat of extinction, it says that virtually everywhere the major threat to a wild species is loss of habitat to a rapidly increasing human population requiring more space in order to build villages and cities and grow more food. But starvation and poverty cannot be eradicated solely by increased food and resources at the expense of what remains of the natural world. Any increase in the provision of food and resources must be accompanied by a drastic reduction in the rate of increase in the human population.
