Man is mind, and the situation of man as man is a mental situation... The mental situation of our day is pregnant with immense dangers and immense possibilities; and it is one which, if we are inadequate to the tasks which await us, will herald the failure of mankind.

— Karl Jaspers

Since then: WWII, Holocaust, Hiroshima and Nagasaki, wars, postmodernism, egomaniacal consumerism, destruction of ecosystems, mass extinction of species, climate change, rising inequality, decline of democracy, renaissance of authoritarianism, digital dictatorships, etc. We failed and failed again.
