The reason why it is half-baked materialism is mainly because it is not thorough. It insists on materialism in the view of nature and idealism in the view of history.

Old materialism is metaphysical materialism, also called mechanical materialism. It recognizes the primacy of matter, which is materialistic, but it thinks that everything is isolated, static and unchangeable, which is mechanical or metaphysical.

Time and space are not the storage places of things, but the existence forms of moving things. Time and space are inseparable from things, not the relationship between storage and being stored, not the relationship between big and small.

To separate them is to treat them as things that exist in isolation from each other, so this is the space-time view of mechanical materialism.

Extended data:

The shortcomings of the old materialism:

Metaphysics: treating all problems with isolated, static and one-sided thoughts.

2. Mechanization: Explain all phenomena, including human activities, with the principle of mechanization.

3. Incompleteness: The old materialism insisted on materialism in the view of nature and idealism in the view of social history.

4. Replace the general with the individual, and replace the material category of philosophy with the material concept of natural science, without making a concrete analysis of specific problems.
