Professor Singer speaks plainly and gives the reading public a basis for establishing a firm ground in reason for moral judgments. As always, he is thorough in his exposition. He manages to achieve at once great scope and great depth in fundamental issues in moral philosophy. A reader will find in Singer's scrutiny of the many facets of moral judgment an extraordinary perceptiveness for the main lines of argument for major issues, as well as for subtleties that too often go unnoticed. The barbs of moral scepticism are deflected with deft skill. A patient and attentive reader will be rewarded with entry into a larger but relevant world of illumination in matters central to the life of reason in morality.
