There is, in fact, no such thing as social, economic, and political conditions (or forces) alone; they are always part of a context of perception and feeling. Nor are there values, ideas, beliefs – alone; as a social matter, they are always interconnected with “material interests.” Power is also an idea; justice is also a force. Neither causes the other, in the physical-science sense of that word.
