Do we survive as a species of 10 billion people on Earth? Then we must build our society better and quicker than so far using our collective brain. Freedom, inclusion, and respect for all?

There is too much egoism in the world and too many groups do not meet each other anymore. Nation-States and related geopolitics are old thinking.The secular, liberal, democratic society seems to be the best political model we developed measuring the decrease of violence, discrimination and repression, and the increase in freedom of speech, human rights and dignity, but the number and quality of real democracies is decreasing and alternatives are available (China). The rich, and the populists, ‘buy’ the society. A democracy needs maintenance. More on the website: www.tragedyofdogmas.nl
