This article examines the advances made by neuroscience in the attempt to find an answer to the question regarding the origin and foundation of moral judgements and of human behaviour in compliance with them. The conception of the brain as something dynamic and capable of adapting to the social and cultural surroundings is seen to be an important point for philosophy. At the same time, the complexity of ethical issues that cannot be reduced to observations based strictly on neurons alone also becomes quite apparent. Nevertheless, scientists and philosophers should get together and communicate with one another so as to be able to pose their questions with greater rigour and take advantage of each other's respective knowledge.
