In this work, we try to find answers, in clear and simple language that agree with the common sense of most people, to questions such as: What are the basic aspirations of human being? What are goods and values? Can we aspire to find truth, beauty, goodness, love and happiness? Is there a commonly accepted concept of good and evil? What are the motivations that move human beings to do good? Are there universal moral laws? Is man good by nature? Does the problem of moral and social evils have a solution? What is conscience? Can ethics offer a solution to current human problems?
