First published in 1960, The Prime of Life offers an intimate, captivating picture of Simone de Beauvoir in her twenties, thirties and forties. Beginning as a recent graduate from the Sorbonne teaching high-school girls, we see de Beauvoir revel in the freedom her new financial independence brings. We see her and Jean-Paul Sartre recognise the powerful romantic and intellectual partnership they have found in one another, as they fall in love and define their own unconventional parameters. The Second World War comes, bringing austerity, violence and questions of the reality of freedom and individual responsibility into de Beauvoir’s life. As relevant and penetrating as when first published, The Prime of Life offers rare insight into a truly fascinating mind.
