Human Idealism

I talked about Idealism. Historically, philosophical Idealism is usually associated with enlightenment era Idealism. This was mostly metaphysical Idealism; to give a simplified description, the idea that ideas and thoughts are the root of the universe and existence, not physical matter and energy. Regardless, the word Idealism generally means a worldview in which ideas are seen as the root.
When I talk about Idealism, it's maybe better to call it Human Idealism. I believe that rationality is the driving force of human existence and personality, and therefore of human society. Ideas and ideals appeal to rationality and are its most powerful agents. Therefore, Ideals are the root of human existence and society.
This clashes with two theories that are widespread.
One, the materialistic view of society. The idea that economic or political structures define society. The king, the prime minister, big business. I rather believe a society's ideology totally defines it's structure. Its ideas, its concepts, its thoughts. There were kings until the idea of monarchy died. There will be the power of big business until the idea of Capitalism dies.
Second, the psychoanalytical idea of the subconsciousness. The idea that humans are ruled by unconscious, hidden, lower urges and desires. I think on the contrary that humans are ruled by rationality, by the very conscious ideals and ideas they have. Rationality is always a much stronger force in human personality than the most powerful desire. If this is not the case for some humans, it is because their rationality is not very developed yet.
This is the idea of Idealism. Ideals and rationality are the true roots of being in this human world.
