Thanks to the present translation of the late M. Merleau-Ponty's PhÉnomÉnologie de la perception,¹ preceded by those of J.-P. Sartre's L'être et le nÉant² and M. Heidegger's Sein und Zeit,³ the three principal documents of existential philosophy are now available in the English language. It would be most desirable to have them supplemented by that of E. Husserl's Die Krisis der europäischen Wissenschaften und die transzendentale Phänomenologie⁴ which, in a certain sense, provides the connecting link between phenomenology in the strict Husserlian sense and the existentialist offspring.
