Query: A classic of phenomenology

This early work of Merleau-Ponty is one of the great works of phenomenology. It is a tremendously rich book, and contains a great deal of thought not reproduced elsewhere in his writings. He takes phenomenology in a different direction from that of Husserl, Heidegger and Sartre, though he remains in dialogue with all three throughout. Late 20th century philosophy owes much to Merleau-Ponty, and this is a key work in understanding his thought. In my own opinion, it is one of the great books of philosophy, and the translation by Colin Smith is excellent. I highly recommend it, as you may have guessed.
