Idealism

Idealism is a philosophical concept that posits ideas prevail over matter, and as such that reality is subjective, dependent on one's experiences.

It exists in contradiction to materialism, which forms the basis of scientific socialism and generally the scientific outlook of the world.

History

Idealism and materialism have existed as schools of philosophy since at least Ancient Greece, though these theories took centuries to mature. In this society, materialism was merely the idea that everything in the world is made of matter.

Yet idealism came to exist somewhat naturally. The first humans observed phenomena that they didn't understand (such as storms, volcano eruptions, seed germination...) and attributed these activities to unseen spirits, which formed the basis of the first human religions, also known as animism (the belief that items, places, and things are inhabited by spirits).

Later, as humans experimented and learned about the world, animism would turn into polytheism, and then into monotheism and God. The idea of the spirit (or soul) is still at the centre of idealist thought.

Berkeley, a philosopher of the 18th century, is perhaps the person who reached the highest stage of idealism as a philosophy and has developed it to its end.

Theories and shortcomings

Following Berkeley's theories, he claimed that reality only exists in one's head as, for example, some may find an item to be heavy while others, who are perhaps stronger, will find it to be quite easy to carry.

Yet the weight of an item is an objective quality; it weighs the same no matter who picks it up, and no matter how it feels in their hand. While there are subjective properties to an item (taste, size, shape, colour for example), Berkeley claimed that objective properties were in fact subjective. This means reality does not exist and science would be unable to exist if that were true. Or in other words, while humans see the sun as a yellow-white disc with rays (when seen from the Earth), science was able to determine that it is neither a disc nor yellow-white, nor does it have rays. The sun exists in an objective reality independent from our subjective interpretations. In the materialist interpretation, we are not discussing the properties of things, but their existence.

Idealists therefore claim that mind creates matter. Therefore, it follows that the world does not exist outside of our thoughts. And ultimately, our ideas create things, where things are the reflection of our thoughts. An apple becomes an apple only when we apply several properties to it such as colour, shape, taste, etc. Yet, as we have seen in the example of the Sun, things exist in an objective reality that may be completely different from our subjective interpretation.

Religious ties and opposition to science

Ultimately, idealism will always turn to God to justify its arguments. As it was born of human religious beliefs (themselves based on ignorance of the material world), it can only exist when supported by these beliefs. If it follows that the world exists only in our mind, then how can science explain that the world existed before humans? Idealists will say that animals existed before humans and that perhaps they could think. But we also know that the world existed without any form of life for millennia. Thus idealists will claim that God has always existed, and that God is capable of thought. When choosing between idealism and materialism, one has to choose between God and science.

Moreover, how does idealism explain human consciousness and the existence of thought? They claim God imbued human beings with a soul, an immaterial concept that has yet to be observed, and that this soul allows us to think and therefore create reality and act upon the world. In the materialist framework, we understand that thoughts are created by the brain, a material object.

God is an ultimate being, an affirmation that cannot be proven (and will not be proven by idealists, who simply accept that God exists). Science however demonstrates through practice and experience that the world exists objectively.

Dialectics

In the scope of dialectics, idealists claim that ideas move things forward. That people had the right ideas at the right time and this moved society forward. For example, the steam engine was invented at the right time and thus allowed productivity to flourish, which led to capitalism establishing itself as the dominant mode of production.

In Hegelian idealism, it is ultimately God that is responsible for dialectics, much in the same way it was for Berkeley.

Yet ideas are dependent on material conditions. The steam engine could not have existed before steam was understood to create power which could be harnessed to move gears. It also had no practical use before the relations of production were organised enough that it became viable to use steam machines.

These same material conditions also create the ideas that people are capable of forming. Scientific socialism could not have existed as it does today before capitalism, since it is made possible with the productive capabilities of factories and steam machines (now electronic). While thinkers of the Middle Ages and earlier could have invented something close to communism (say common ownership of the means of production), they could not have foreseen capitalism and the machines it would use. They could not have foreseen the existence of the bourgeoisie and proletariat.

Liberalism

Liberalism is an idealist ideology.

Opposition

Materialists, such as marxists, oppose idealism as the two are in contradiction. Moreover, materialism represents the scientific conception of the world (which when applied to socialism forms scientific socialism) whereas idealism represents the utopian conception of the world.
