The function of the Quaternary Imprint is to publish material for a level of education and practice commensurate with the previously unrecognised coherent and comprehensive philosophy articulated deliberately by William Shakespeare's in his 1609 Sonnets as the basis for his Folio of thirty-six plays and four longer poems.

    The works of Shakespeare are the basic text for the Quaternary because only his works, and particularly the Sonnets, are capable of providing a consistent and comprehensive expression at a quaternary level of understanding. Other proto-quaternary thinkers have made specific contributions toward such a sensibility but the philosophical dimension of their work has been limited to one or other aspect of the complete philosophy available in Shakespeare's Sonnets, plays and poems.

    As there already exist hundreds of publishing houses dedicated to the level and needs of Tertiary scholars (and others), Quaternary Imprint will only consider for publication material that is completely post-Tertiary. Because Shakespeare's philosophy has not been previously recognised in 400 years of University or tertiary level scholarship it seems appropriate to expect prospective authors to operate beyond the level of learning currently available in tertiary institutions world-wide.

    The Quaternary Imprint and Quaternary Institute websites herald the need to establish a level of tuition in the Quaternary sensibility appropriate for a global constituency. Publications from Quaternary Imprint will formulate the conditions for a quaternary level of learning as a natural step up for those, particularly doctoral graduates and professors, who realise they have reached the limit of tertiary methodology.

    Quaternary Imprint oversaw the publication in 2005 of William Shakespeare's Sonnet Philosophy of 1760 pages in four volumes, by Roger Peters. As announced on the Quaternary Imprint home page, further volumes are now ready for publication.

    Beginning in March 2017 with Shakespeare's Global Philosophy, an effective summary of the four volume set with additional insights, and followed by Shakespeare and Mature Love and Shakespeare's Philosophy: Pictorial Volume the next few years will see a number of volumes detailing aspects of the philosophy using differing methods and different formats.

    As each volume appears, the Quaternary Imprint website will present a number of pages to introduce aspects of each publication. A brief description of the contents of each page is available at Quaternary Imprint Site Map.
