All Religions Are One — William Blake's earliest philosophical tractate — nine propositions arguing that the Poetic Genius is the universal source from which all religions and all human faculties derive.
Songs of Innocence and of Experience — William Blake's contrary-states poems — Songs of Innocence (1789) and Songs of Experience (1794) — the Lamb and the Tyger, the chimney sweeper and the sick rose, forty-seven lyrics mapping the two contrary states of the human soul.
The Marriage of Heaven and Hell — Blake's visionary prose poem of 1790, proclaiming the holiness of Energy and the unity of contraries — the founding document of the Aquarian imagination.
There Is No Natural Religion — William Blake's companion tractate to All Religions Are One — two series of propositions arguing that the senses alone cannot contain truth, and that infinite desire implies an infinite perceiving soul.
