True. Rousseau and Blake both believed human beings are inherently good.
Explanation:
Rousseau was primitivist in his belief and said that humans are inherently good and must go back to the beginning of civilization to live by this inherently good and moral instinct in an anarchic society.
This philosophy was not what Blake subscribed to entirely but did believe in the virtue of humanity. He in turn believed in living in the present world but being in touch with the nature and not forgetting the true roots of humanity.
