The present book seeks to give an exposition as well as a critical evaluation of the philosophical content of phenomenology and existentialism. It seems to me that there are not enough books on the subject which provide an ex- haustive treatment of the subject. Students and readers interested in the sub- ject often remain perplexed, as the ideas are not generally expressed clearly. I have tried to remove that difficulty as far as possible. It is sometimes thought that analytic philosophers and philosophers ow- ing their allegiance to phenomenology and existentialism move in different directions. In my critical discussions I have tried to show that all philoso- phers are concerned with the same problems. Only their approaches are not always the same. Perhaps an analytic approach to phenomenology and exis- tentialism can narrow down the gaps in philosophical understanding. In the book I have tried to indicate how phenomenology extends into ex- istentialism. Even the so-called non-phenomenological existentialist think- ers have a distinctly descriptive approach akin to phenomenology. Towards the end I have tried to develop phenomenologico-existentialist account of human reality. It is only a rough sketch of how we can work in the area of analytic phenomenology and I have tried to organize the available materials, although I am afraid I have not been able to cover all the material. Even then if readers get a fair idea of the subject from a study of the book, my labour will be rewarded.
