The Mental Traveller is a poem by William Blake. It is part of a collection of unpublished works called The Pickering Manuscript and was written in a manner that suggests the poem was to be read directly from the collection.
The poem is about travelling in the realm of the mind. Blake generalizes here "about the spiritual history of mankind out the experience of his own spiritual history."[1] It can be also understood as a cycle history of relations between society and idea of liberty in the form of a male and female that grow older and younger in opposition to the other experiencing such changes. As a whole, the poem portrays conflicting ideas that make it difficult for the reader to attach to any given viewpoint.
