It's ironic that, not only do we fail to consciously represent our creator's purpose, we also fail to consciously represent a coherent picture of our own fragmented purposes. We typically act like confused servants to a crowd of waxing and waning drives. If you understand this state of affairs, then you can use the full power of conscious thought and achieve your true purposes better than you otherwise would have. You can strive to be a knowledgeable and effective servant to a crowd of waxing and waning drives.
