Charles Sanders Peirce and Effective Altruism.

When confronted with moral dilemmas, Charles S. Peirce would recommend that we trust our sentiments, not our reasoning. A scientific exploration of ethics may affect our daily conduct but should only do so gradually. Some modern approaches take the opposite stance and deny the significance of moral sentiments. Considering both Peirce and his opponents, I aim to contribute to the discussion of a radical moral theory: effective altruism. Stating that we should strive to do the most objective good we can, effective altruism regularly conflicts with our moral sentiments. In response, effective altruists claim that our sentiments are misguided and should be overcome. Which side is right? Using Peirce's work to answer this question reveals that effective altruism cannot clearly define how it aims to affect our daily conduct. In addition, it seeks to change our sentiments, but may alter them for the worse. Taking Peirce's insights seriously leads us to conclude that we should be cautious of how we adopt effective altruism in our lives—and that while we deliberate this, we should instead trust our sentiments.
