The paper outlines Aristotelian and Aquinian eudaimonistic conception of hap_piness and its criticism in modern ethics in the context of the rehabilitation of this concept in contemporary moral philosophy. On the background of the modern discussion it presents the objectivist theory of happiness in the frame of Neoaristotelian ethics of virtues. In its description the author introduces the inclusive concept of happiness. He defines the true happiness as an optimal relationship between the subject and the world, making a difference between an apparent and a true hap_piness and stressing the function of practical reason in reaching the latter.The principle of the true happiness is true love, which is made possible by the moral virtues considered as good dispositions, supporting the operative human skills. The ideal of happiness works as an regulative idea, which directs the human behavior and gives it its meaning.
