Prompt
"A 19th-century, Victorian-era inspired illustration of a book cover with a title 'The Principles of Ethics' by Herbert Spencer, with a background that subtly incorporates elements representing evolution, morality, and philosophy, such as a faint image of a tree growing in the background, symbolizing social evolution, and a small inset image of a scale of justice, representing the pursuit of justice and ethics, all rendered in a classic, elegant style."
