Matthew Arnold emphasized 'high seriousness' as a defining characteristic of great literature. He believed that literature should deal with profound moral and philosophical themes, serving as a guide for human conduct and a source of cultural enrichment in an increasingly secular and industrial society.

Cardinal John Henry Newman, John Keble, and their associates were the central figures of the Oxford Movement. This movement aimed to restore high-church principles and traditional theology to the Church of England. Through their writings, particularly the 'Tracts for the Times,' they sought to influence the religious and intellectual life of Victorian England, emphasizing the historical continuity of the Church.

Matthew Arnold argues that the critic must maintain 'disinterestedness', meaning the ability to remain detached from political, practical, or personal biases. By keeping the mind free from ulterior motives, the critic can objectively see the object as it really is, thereby fulfilling the true function of criticism in society.

The term 'pathetic fallacy' was coined by the Victorian critic John Ruskin in his work 'Modern Painters' (1856). It refers to the literary device where human emotions or characteristics are attributed to inanimate objects or aspects of nature, often to reflect the internal state of a character or the mood of a scene.

While Arnold discusses criticism in several works, 'Culture and Anarchy' is a seminal text where he explores the relationship between culture, poetry, and the intellectual health of society. It remains a cornerstone for understanding his critical framework and his vision for the role of literature in modern life.

Matthew Arnold introduced the 'touchstone method' in his essay 'The Study of Poetry'. This critical approach involves comparing passages from a work of literature against short, established 'touchstones'—lines or expressions from great classical writers like Homer, Dante, or Shakespeare—to determine the quality, truth, and seriousness of the work being evaluated. It serves as a standard for judging the aesthetic and moral value of poetry.

While 'Dover Beach' is a Victorian poem, its profound sense of spiritual crisis, loss of faith, and existential uncertainty—often described as an undertow of nihilism—anticipates the disillusionment central to 20th-century Modernism. The poem captures the transition from Victorian certainty to the fragmented worldview that would define the modernist movement, distinguishing it from the more optimistic or structured works of its contemporaries.

'On Liberty' is a seminal work on individual freedom and government intervention, written by John Stuart Mill in 1859. It advocates for the protection of individual liberty and the limitation of state power, making Mill a pioneering figure in liberal thought.

Matthew Arnold published 'On Translating Homer' in 1861, based on a series of lectures he delivered at Oxford. In this work, Arnold evaluates various translations of the Iliad, arguing that a successful translation must capture the 'grand style' of Homer. He emphasizes that the translator should aim for simplicity, directness, and nobility, reflecting the original Greek epic's tone rather than focusing on archaic or overly ornate language.

The 'Sea of Faith' is a metaphor for the declining significance of religion in the modern world, as the speaker laments the loss of faith and the increasing secularization of society.
