Although this was first published in 1989 — 9 years after Sartre passed away — this was actually first written in 1948, and acted in some ways as a response to Heidegger’s Essence of Truth, although I would also argue that this book served as some closing remarks and afterthoughts of his earlier works, but also briefly alludes to ideas that he would later expound on.
This text is about 80 pages long, and feels fairly accessible to people mildly familiar with Sartre. The prose can still be quite thick though at times.
The topics in here may not be all that new if you are already familiar with Sartre’s works, however, this text is original enough and satisfyingly stimulating to be considered as its own separate work.
I highly recommend this work, even those who are not collectors of Sartre’s catalogue. This book definitely deserves more recognition.
I really love the part where he mentions on how much you must embrace and accept your actions with the morals and values that you chose to apply, but most importantly, without knowing with definite certainty of what the consequences of your actions will be (regardless of intention), it interestingly can reveal to you and others what your truth is, provided you made it authentically and in good faith. In other words, if people knew in advance what would happen in their lives with the choices they made, how real do you really think that you would truly be? How likely would you still follow the same path and exercise your same values?
The most genuine version of yourself is acting as though you have no idea what will come in the future, while pretending that nobody is watching you.
