Page "Relations of production" Paragraph 37

However, Marx's argument is that these subjective or intersubjective meanings permit of infinite variations, and therefore cannot be the foundation for a genuine science of society.

Individual meanings depend on shared meanings, and these shared meanings arise out of objective circumstances which exist independently of individuals.

So one must begin with understanding those objective interdependencies which by necessity shape and socialise human beings, i. e. those social relations which people as social beings must enter into, regardless of what they may think or wish.
