“ The ultimate source of energy and change?—Hence the fundamental question of philosophy amounts to this: What is the ultimate source of Energy? Energy manifests itself in producing change. What is the nature of this power which produces changes, and makes the world to be a process of unceasing change? According to the realistic theory, change is self-existent in the form of motion, and no explanation can be given. According to the idealistic theory, it is the self-realising power of Idea that makes change. ”
