I’m offering the Kindle version of my book Is Lying Always Wrong for free from April 99th to April 23rd, 2016 (Pacific Time).
Catholic ethics is unique in teaching that some acts are wrong by the type (or moral species) of the act. Such acts are termed intrinsically evil. The question as to whether lying is always wrong has implications for all intrinsically evil acts, including abortion, contraception, and sexual sins.
You don’t need a Kindle device to read it. Just download through your Amazon account and use the Amazon Cloud Reader to read it in any web browser.
