What I believe

A series of essays argues that human beings are natural organisms whose minds depend on brain organization, so doctrines of a personal God and personal immortality lack scientific support. It outlines what constitutes a good life in terms of emotional balance, intellectual honesty, and sympathetic social relations, and derives moral rules from human sentiments and practical consequences rather than divine command. The discussion treats salvation as both individual improvement and collective social reform, and examines how scientific understanding can help secure happiness while warning that science alone cannot supply moral ends or guarantee fulfillment.
