This book tackles the key theoretical and practical challenges confronting humanity as it stands at the brink of self-destruction.  Its wide ranging investigations counter the enfeeblement of thought and action by showing how reason can free itself of bondage to the principle of non-contradiction and reduction to calculation, how the reigning dogmas that block true knowledge of mind and obscure the limitations of artificial intelligence can be overcome, how language enables rather than limits the freedom of thinking and conduct, how the concrete context of action cannot rob it of its autonomy, why capital punishment is illegitimate, how caste can be overcome and religion can be reformed to be compatible with democracy, how fascism can be philosophically refuted, and how nuclear and climate change Armageddon can be averted in an era of globalization.  This book is essential reading for all scholars, researchers and advanced students of political philosophy and German idealism.
