Ask Lao Tzu whether to take the job. He answers from the Tao Te Ching. Consult Epictetus about how to handle a difficult situation with a co-worker and he cites his Discourses. Answers show a reference to the philosopher's original work to support their claims: tap the reference to read that passage as a one-line gist, a short summary, or the translator's original text. Who's here? Buddha, Lao Tzu, Confucius, Plato, Aristotle, Epicurus, Epictetus, Marcus Aurelius, Seneca, Nietzsche, Marx, Thoreau, Benjamin Franklin, King Solomon, Moses, Paul, Augustine, Thomas Aquinas, Martin Luther and John Calvin. More being added, just ask! Group Debates Start a chat with both Nietzsche and Aquinas and ask about suffering. Get their best statements and counterarguments to each other to help you see the question from several sides. They reply to you and to each other, supporting their points with citations. Write in your own language Most languages are supported. Write to the Buddha in Arabic and the answer comes back in Arabic, with the Dhammapada verse number. Characters are played by an AI and can be wrong. Citations let you confirm the philosophers' original meaning. 10 free messages a day.
