Tien Cong Tran received his Ph.D. in philosophy with the thesis Heidegger and Nihilism. He translated Heidegger’s Sein nnd Zeit (Being and Time) into Vietnamese (1973). He published twelve books in Vietnamese and four books in English. According to Heidegger we are still not thinking. Heiddegger wants to open a new way of thinking. However Tien Cong Tran has discovered that this new way of thinking of Heidegger is already abundantly present in the teachings of the I Ching, Lao Tzu, Confucius, the Buddha and Jesus. That is the reason why his books aim at introducing a new way of thinking and at the same time re-reading the words of the sages. With this new way of thinking philosophy becomes a study of the Way to happiness.
