Eclipse of Reason (book)

"Eclipse of Reason" is a book by American philosopher Max Horkheimer, published in 1947. In it, Horkheimer explores how reason, traditionally seen as a guiding force for human understanding and progress, has been undermined by social and historical developments. He argues that the rise of instrumental rationality—focusing on efficiency and control—has led to a superficial use of reason, neglecting deeper moral and philosophical concerns. The book critiques modernity and asserts that genuine reason must address ethical dimensions to promote true understanding and human flourishing, rather than merely serving as a tool for domination or manipulation.
