How did James Joyce use stream of consciousness in his fiction?

James Joyce is renowned for his pioneering use of the stream-of-consciousness technique, a variant of the interior monologue that revolutionized 20th-century fiction. While he credited the French writer Édouard Dujardin as an inspiration, Joyce’s innovation was to apply this method more continuously and comprehensively than any predecessor.12

In his fiction, Joyce used this technique to replicate the seemingly random, non-linear nature of human thought. He sought to capture the "myriad flow" of an individual's conscious awareness, including:1
* Half-thoughts and associations2
* Lapses, hesitations, and incidental worries2
* Sudden impulses alongside rational thought2

This approach is most famously realized in his novel Ulysses, where it reveals the inner lives of characters like Leopold Bloom and Molly Bloom. The novel’s final section, a celebrated soliloquy by Molly Bloom, exemplifies the technique through eight massive, unpunctuated paragraphs that convey her raw, passionate consciousness. Joyce also employed this style in A Portrait of the Artist as a Young Man, using it to reflect the evolving emotional state of his protagonist, Stephen Dedalus.324
