These words, repeated by Blake in more than one context, contain the essence of his prophetic message. In itself this happy phrase seems a spontaneous expression of simple delight by a mystical poet. But although in his Songs Blake can speak with simplicity to the heart of childhood he wrestled with the fundamental questions and arguments of philosophy with all the power of his great intellect, challenging the culture heroes of Western civilization and indeed the very premises upon which modern Western civilization rests. Yet he knew that he would prevail; for ‘Truth can never be told so as to be understood and not be believ’d.’ (K. 152)
