Espionage career Hagger worked with British Intelligence in the 1960s and early 1970s. He states that John Cecil Masterman, provost of Worcester College while Hagger was there, recommended him for intelligence work. He was interviewed by Charles Woodhouse at MI6's "front office" in 3 Carlton Gardens. In his two volume memoirs, My Double Life he says he declined permanent involvement with MI6, but describes periodic involvement with intelligence assignments spying on Muamar Gaddafi and African national liberation movements such as UNITA, ZANU, ZAPU, and the MPLA.

Academic career He was sponsored by the British Council as a lecturer at the University of Baghdad, Iraq, from 1961 to 1962 and then at the University of Tokyo (1964 to 1965, where he lectured on T.S.Eliot), Tokyo University of Education (now University of Tsukuba), where he taught in the room where William Empson used to teach, and Keio University, a combined post (1963 to 1967), where he was also Visiting Foreign Professor. He was also tutor to Emperor Hirohito’s second son, Masahito, Prince Hitachi from 1964 until 1967. From 1968 to 1970 he was at the University of Libya, Tripoli He wrote for The Times and taught in London. Hagger later became involved in education management and set up and established the Oak-Tree Group of schools, which now comprises three schools.

Otley Hall In 1997 he bought Otley Hall in Otley, Suffolk, and for seven years ran it as a historic house. Between 1998 and 2000 he hosted four casts of Shakespeare’s Globe actors, including Mark Rylance and Vanessa Redgrave, for rehearsal residencies at Otley Hall. He was Secretary to the Shakespearean Authorship Trust, then chaired by Rylance, from May 1998 to February 2005.

Philosophical system: Universalism Hagger described in his long poem ‘The Silence’ (1965–1966) and early sonnets how he underwent a centre-shift from his rational, social ego to a deeper self, had his first of many experiences of the Light and found he was on a Mystic Way that would last 30 years. He argues that a central theme of his works is the human search for unity, which he links to themes he identifies in world literature, history, philosophy, religion and politics. He argues that his works reflect a lifelong quest to uncover the unity of the universe and humankind in verse and prose, a vision he calls Universalism.

Literary works Hagger is the author of 65 books. He describes his philosophical system, which he calls Universalism, as an attempt to reveal the oneness of the universe and relate it to seven disciplines within a single framework: literature, mysticism, philosophy and science, history, comparative religion, international relations/statecraft, and world culture. Hagger's writings are interconnected and cross-disciplinary, and can be explored within each discipline: Literature, poetic works which began in the Modernist style but adopted more traditional stanzaic form, rhyming and blank verse (A Baroque Vision) after Hagger met and corresponded with the sonneteer Edmund Blunden in Japan in 1964 and visited Ezra Pound in 1970, comprising 2,551 poems (including 421 classical odes and 567 sonnets), two poetic epics (Overlord and Armageddon), two mock-heroic poems, five verse plays and three masques (among the largest collections by any poet); 1,425 short stories, diaries, autobiographies and literary travelogues; and a prose work (A New Philosophy of Literature, subtitled The Fundamental Theme and Unity of World Literature) in which he argues that the fundamental theme of all world literature is a conflict between two antithetical traditions (the quest for the One and condemnation of social follies and vices), and their unification in the Baroque; Mysticism, spiritual autobiographies describing the experience of the Light such as My Double Life, and metaphysical explorations; Philosophy and science, works (The New Philosophy of Universalism and The Algorithm of Creation, which is subtitled Universalism's Algorithm of the Infinite and Space-Time, and a Theory of Everything) outlining Universalism, a system that identifies a law of order in the universe, rooted in the infinite and pre-dating the Big Bang; History, studies of 25 civilizations that go through similar stages (The Fire and the Stones and The Rise and Fall of Civilizations); investigations into the influence of secretive organizations on world events (The Syndicate, The Secret History of the West and The Secret Founding of America); and eyewitness accounts; Comparative religion, a work (The Light of Civilization) on the shared mystical essence, the experience of Light, across traditions; International politics and statecraft, works of political philosophy (The World Government, World State and World Constitution) proposing a World State and altruistic global governance; and World culture, a work (The Secret American Destiny) setting out cultural unity in the seven disciplines of world culture across civilizations.

His major works include The Fire and the Stones (1991), The Secret Founding of America (2007), The New Philosophy of Universalism (2009), World State (2018), and The Algorithm of Creation (2023).

Critical reception Nicholas Hagger's work has received a varied response from reviewers. Commentators have frequently noted the ambition and scale of his output across poetry, philosophy, history and memoir. Supportive reviewers have praised the breadth of his imaginative vision and the scope of his intellectual aims, while critics have raised questions about the accessibility of his style, the speculative nature of his philosophical system, and aspects of his historical methodology. But reviewers generally acknowledge the distinctiveness and scale of his approach, and the coherence of his overarching themes.

Poetry Reviewers have recognised the ambition and scale of Hagger's poetry, particularly his epic narratives influenced by classical models such as Homer, Virgil, Dante and Milton. His work has attracted attention for its metaphysical themes and philosophical consistency, and The American Journal of Modern Literature has published recent articles on his poetry. Supportive commentators have praised the breadth of his imaginative vision and the coherence of his metaphysical concerns. Kathleen Raine and David Gascoyne expressed support for Selected Poems: A Metaphysical’s Way of Fire in 1991, and Poet Laureate Ted Hughes commented positively on his approach and on Overlord in correspondence between 1993 and 1998.

Critics have questioned the accessibility of his style, the density of his metaphysical material, and the extent to which his epics align with the classical traditions he invokes. Hagger sought to revive the epic form after discussing Overlord with Ezra Pound in Rapallo in 1970 and epic blank verse with Christopher Ricks in 1993, and integrated themes associated with the Metaphysical poets. His style has been described as distinctive and ambitious, diverging from prevailing minimalist and postmodernist trends. Some commentators argue that the clarity of his purpose and commitment to large-scale visionary projects offset the length and didactic tone of some works. Others have highlighted the distinctiveness of his voice and the scope of his literary aims. His engagement with universal themes – religion, philosophy, history and politics – has led critics to view his poetry as part of a coherent metaphysical undertaking. His correspondence with Hughes and Ricks further situated his aims within a modern revival of the epic tradition. His work draws on cosmology, comparative religion, mystical traditions and historical poetic lineages, and has been described as distinctive within contemporary British poetry for its large-scale structure and engagement with universal themes.

Philosophy During his time in Japan, Hagger frequently discussed philosophical ideas with the philosopher E.W.F. Tomlin, a British Council Representative and associate of T.S.Eliot, whose interests helped shape Hagger's early intellectual direction. His own philosophical system, which he terms “Universalism”, has been described as a wide-ranging, expansive intellectual synthesis drawing on comparative religion, metaphysics, cosmology and history. Reviewers have noted the scale and interdisciplinary scope of the project and its attempt to articulate a unifying perspective across multiple fields.

Some commentators regard Universalism as speculative and outside mainstream academic philosophy, while acknowledging the ambition of its integrative aims. In 2023, physicist Bernard Carr, known for his work with Stephen Hawking, signed the certificate awarding Hagger the 2023 Scientific and Medical Network book prize for The Algorithm of Creation, recognizing the system's contribution to discussions of consciousness and cosmology (see Awards).

History Hagger's awareness of world history and culture was deepened by his extensive travelling while working at foreign universities. Responses to Hagger's historical works have been mixed. Supportive reviewers have praised the ambition of his large-scale surveys and his attempt to identify long-term patterns in the development of civilizations, noting the coherence of his overarching narrative. The historian Asa Briggs, who had introduced interdisciplinary approach at the University of Sussex, described The Fire and the Stones as a tour de force. An 11-part online series titled Theoretical History focused on Hagger's study of 25 civilizations and grouped him with Spengler and Toynbee. Critics have questioned aspects of his methodology, including reliance on broad generalizations and the integration of metaphysical ideas into historical analysis. Nonetheless, reviewers have recognised the scope of his undertaking and the distinctiveness and coherence of his narrative approach within contemporary historical writing.
