In The Ecology of Freedom, my critique of what is called civilization and industrial society is massive, and my attack upon [Karl] Marx's commitment to it as a necessary stage in human progress and the domination of nature is very sharp.

If the State does not enjoy a monopoly of violence, which then gives it the power to order people's lives and to compel them to obey decisions over which they have no control, or just limited control, then I think you have a consistently libertarian society.

I feel that if people investigate the emergence of government, of State power - if they examine the logic of State power historically, and more specifically in the United States - they will find that the concept of limited government is not tenable once they adopt some type of libertarian principle.

I believe that the American people should defend themselves if any attempt is made to take over the government by coup d'etat, whether by the military or the Marxists or any people who profess to be anarchists.

To speak of 'limits to growth' under a capitalistic market economy is as meaningless as to speak of limits of warfare under a warrior society.

My thinking is very flexible, and I hope that it will remain flexible and creative as long as biology permits me to think and that I will remain a rebel all my life.

Until we become the architects of a society that is truly free and ecological, it will always seem that when the human brain is not adaptive, it is more often destructive than creative.
