Summary

TLDRNatural law ethics, developed by St. Thomas Aquinas, holds that reason is the source of moral law, guiding humans to do good and avoid evil. Aquinas believed that the 'good' aligns with human nature and is discernible through reason and conscience. He identified three natural human inclinations: self-preservation, just dealing with others, and propagation of the species. Violating these leads to immoral acts. Aquinas also proposed the 'principle of double effect,' addressing moral dilemmas where actions yield both good and bad outcomes, with all conditions needing to be met for an act to be morally right.
