Final answer:
The quote regarding Charing Cross was made by Samuel Johnson, not Charles Dickens, William Shakespeare, or Oscar Wilde.
Step-by-step explanation:
The statement "I think the full tide of human existence is at Charing Cross" is correctly attributed to Samuel Johnson, not Charles Dickens, William Shakespeare, or Oscar Wilde. This memorable quotation was made by Johnson in conversation with James Boswell. Samuel Johnson, an eminent English writer and critic of the 18th century, expressed his perception of Charing Cross in London as a focal point representing the vibrant and dynamic essence of human life during that era.
While Charles Dickens, William Shakespeare, and Oscar Wilde are renowned literary figures, this specific insight into the significance of Charing Cross belongs to Samuel Johnson, emphasizing his keen observations and reflections on the cultural and social milieu of his time.
