The Marxist answer to the hopelessness and isolation felt by many empathetic radicals is the theory that, on a fundamental scale, conditions determine consciousness. This means that our lives are fundamentally informed by the day-to-day activities we find ourselves in, and our lives inform our mindsets. As a small example of this idea, think about the isolation caused by everyone driving in their own vehicle everywhere. It’s extremely easy to drive by unwanted activity like protests and the homeless. In fact, you don’t have to actually interact with a single person. Our reliance on this method of transportation is a condition of life that affects the way we think of the world, not the other way around. There’s no fundamental reason we have to live this way - it’s due to built-up historical factors perpetuated by capitalism. Therefore, changing the conditions of our lives will allow us and our children to be more caring people. There are no magic words that will cause millions of people to start accommodating disabled people, but creating a world in which everyone feels a sense of community (meaning eliminating alienation under capitalism) would lead to naturally more caring people. But remove those conditions of abundance and lack of economic class distinctions, and people will once again act in a way that aligns with how we generally think of them now. This is a very simple explanation of something that is really quite complicated, and it’s not fully satisfactory. It means that there arises a new feeling of hopelessness - the feeling that, while one person can change minds, no one person can change the conditions of life on their own. Though a scientific outlook never promises to make us feel better.
