Seana Shiffrin, “Speech Matters: On Lying, Morality, and the Law” (Princeton UP, 2014)

It is generally accepted that lying is morally prohibited. But theorists divide over the nature of lying’s wrongness, and thus there is disagreement over when the prohibition might be outweighed by competing moral norms.There is also widespread agreement over the idea that promises made under conditions of coercion or duress lack the moral force to create obligations. Finally, although free speech is widely seen as a primary value and right, there is an ongoing debate over the kind of good that free speech is. In Speech Matters: On Lying, Morality, and the Law (Princeton University Press, 2014), Seana Shiffrin ties these issues together, advancing a powerful argument regarding the central role that sincerity and truthfulness play in our individual and collective moral lives.
