Perfect. I'm glad.
What we just talk about here, is what we call "the material conditions of existence".
"Material conditions here" means everything that allows us to live and to think and the environment in which we do all of that. (our body, the strenght of our body, our time, our mental state, our living conditions, the people around us, our family, our friends, our laws, our biology, our institutions and many many more....)
Materialists, like me, think that ideas are not the only things that shape society, but more than everything how those material conditions of existences are organized and distributed concretly in society.
For us, ideas matters, but they take root in the realities of the material conditions of existence of the world (who has the food, who has the houses, who controls the factories, who has time to learn, who has the power etc.)
For example: If we have to work 12 hours a day, we won't have the same freedom to study or make other project as someone who doesn't have that load of work.
Do you understand what I'm saying or do you have any question ? (I'm not asking you to agree just yet).
