&"We are all confronted, at one time or another, with choices as to what sort of life we will lead.&" So Tzvetan Todorov begins Frail Happiness, an important interpretation of Rousseau, one suffused with Todorov&?s own moral seriousness and intellectual depth. While ranging widely through Rousseau&?s corpus with skill and scholarly authority Todorov returns, again and again, to the fragile yet persistent hope for human happiness.
