3. Does "assimilating them" mean "understanding them"?

Context:
Socialist Realism proposed that art should:
picture life, but not as it is so much as life as it should become, life worth emulating… that art should picture reality not in its individuality but only as it reveals larger social significance… that art should picture reality as progress toward the future and so represent social struggles positively. It should carry an air of optimism… art should focus on contemporary life, creating pleasing images of new social phenomena, revealing and endorsing new features of society and thus aiding the masses in assimilating them.
