text_A: Empedocles noted the limitation and narrowness of human perceptions. We see only a part but fancy that we have grasped the whole. But the senses lead to truth; thought and reflection cannot inspect the thing from every side. It is the business of a philosopher, while laying bare the fundamental difference of elements, to show the identity that exists between what seem unconnected parts of the universe.
text_B: If you use only thought and reflection, will you find the truth?
NO.
