Is there a missing moral component at the root of happiness? The ancient Greeks definitely thought so, and it turns out that genomic research conducted by Barbara Frederickson, which Winton Bates writes about at his excellent blog Freedom and Flourishing, indicates that we may be biologically wired for what they called eudaimonia (from daimon, or true nature). Differing from hedonism (pleasure or self gratification), eudaimonia is often translated as flourishing or living well, with a sense of noble purpose, virtue, and connection to others.
In other words, real happiness is impossible without virtue - or arete in ancient Greek. Arete means excellent character, or reaching your highest human potential. Eudaimonia not only protects our physical and mental health at the cellular level, it may lead to a long term, more profound sense of well being.
So what do we do if we want to experience eudaimonia? How do we reach our highest potential?
There are 3 concrete steps that you can take to be happy in the ancient Greek sense. First, you must acknowledge that virtue is necessary for happiness. Eudaimonia is about more than just feeling good, it is about becoming the best person that you can be. Second, you must do the inner work that is necessary to truly "know yourself," as Socrates said when he quoted the Delphic Oracle. And finally, you must take action and apply your unique talents and gifts in life for the good of yourself and others.
