Ideas shape the world more decisively than the interests, institutions, or political arrangements that seem more immediately powerful; the most dangerous ideas are precisely the ones that never have to justify themselves. This domain covers the intellectual conditions of modern life: the collapse of shared moral knowledge, the mechanisms by which ideas propagate and govern, and the cultural forms that fill the vacuum when genuine meaning becomes inadmissible. The concepts here orbit a single question: what does it mean to live in a culture that has stopped believing moral knowledge is possible? ## Concepts - [[Moral Knowledge]]: the claim that ethics is a genuine domain of knowledge, and what Western intellectual culture has abandoned by rejecting it - [[Power of Ideas]]: how ideas rule the world more than interests do, and why the most powerful ideas are the ones that never need to argue for themselves - [[Consumer Culture]]: what fills the void left by the collapse of moral knowledge (branding, slogans, and the cute) and why none of it can bear the weight it is asked to carry - [[John Maynard Keynes]]: the economist whose observation about practical men and defunct economists is the sharpest formulation of how ideas outlive their originators - [[Andy Warhol]]: the Pop Art figure whose fifteen-minutes-of-fame observation diagnoses the modern scramble for significance in a media-saturated world ## Cross-domain connectors - [[Moral Knowledge]]: the collapse of moral knowledge in the secular university is the direct backdrop for Willard’s account of why [[Discipleship]] and [[Christian Formation]] matter; the two domains are in conversation
