Philosophy confronts two existential crises: the threats to its existence from scientists like Stephen Hawking who claim that philosophy is dead; and the threat to life itself from catastrophic climate change. The essay's first theoretical part critiques Nietzsche's claim that philosophy's primary function is to guarantee the future of life. The essay's second practical part claims that philosophy must meet the challenge of life's extinction through a revised model for ethics in education. Taking its start from recent conceptualizations of philosophy as a 'field discipline,' this part considers African American models for delivering ethics in education to under-resourced communities. The third part shows how these theoretical models may be actualized in the practice of an African field philosopher.
