The goal of this course is to get a better philosophical understanding of some important notions in the field of ethics. The questions we deal with are such as: Are we moral beings? Do we have to be good? Why? How do we know what is good? How can we justify our actions? What is the role of reason, of emotions, of society and of environment in our moral life? Should all human beings have the same moral values? Is there any connection between being happy and being good?
