1. Sometimes there are conflicts between scientific progress and ethics. Should scientists care about the ethical implications of their research? Should scientific progress ever be halted on the basis of ethical concerns? Should scientists have ethical training? If so, what would their ethical training be like? How should scientists respond to ethical concerns when there is so much controversy about what is ethical and what is not ethical? How can anyone know what is ethically acceptable and what is ethically wrong when there is deep disagreement? If there is deep disagreement, with no uncontroversial position in sight, why should scientists try to satisfy ethicists?
