what is diamat historically?
why do maoists often talk about "materialist dialectics"?
Understanding materialism and dialectics is crucial to understanding anything, for everything is made up of material, and all matter is in a dialectical relationship with all other matter.
Forgive me for giving an irrelevant example, but this just came to me while i was preparing to eat, and I think it makes these concepts easy to understand.
I was microwaving a plate of cheesy beans I had made the other day. For those of you who don't know, cheesy beans is made up of (like all matter) various parts; in this case: vegetables, grains, legumes, cheese, and sometimes fungi. Each of these cheesy bean components---though wholes themselves---are also made up of components. Each bean is made up of a skin and an... inner bean. And both these parts are made up of cells, which are made up of molecules, which are made up of atoms (and so on).
The cheesy beans themselves, though they were a whole, were also a component of a greater whole: my dinner: consisting of cheesy beans and soymilk. My dinner, too, is a component of a whole: my daily caloric intake, which (along with keeping myself at a specific temperature, and fighting disease) is part of a greater whole: my survival necessities.
As for the microwaving process. I don't particularly like microwaves. They always seem to heat up some parts of my cheesy beans too much and others not enough. But recently i found the Power Level button. Now, if there were a mechanical relationship between Power Level, Time, and Temperature Of My Cheesy Beans, the Power Level button would not matter. But, as it were, there is a dialectical relationship between Power Level, Time, The Various Components of My Cheesy Beans, and My Cheesy Beans As a Whole.
Cheesy Beans are a three dimensional object. The microwave cooks the surface area more than it cooks the insides. The main thing cooking the insides is the outside, which is heated, and then gives off heat to the things it touches. Therefore, the lower the power level, the more time it takes for the surface area to heat up, which means it gives off more of its heat to the insides, which means my cheesy beans are heated with greater uniformity, which makes me quite happy.
