According to Aristotle, the ultimate human good is eudaimonia, an ancient Greek word that can be translated as happiness, or flourishing. Eudaimonia comes from a life of virtuous (or good) action. Virtues such as justice, restraint, and practical wisdom cannot simply be taught - they must be developed over time by cultivating virtuous habits. The making of virtuous choices can be developed by using practical wisdom and by recognizing the desirable middle ground between extremes of human behavior.

Ordinary Men is the true story of Reserve Police Battalion 101 of the German Order Police, which was responsible for mass shootings as well as round-ups of Jewish people for deportation to Nazi death camps in Poland in 1942. Browning argues that most of the men of RPB 101 were not fanatical Nazis but, rather, ordinary middle-aged, working-class men who committed these atrocities out of a mixture of motives, including the group dynamics of conformity, deference to authority, role adaptation, and the altering of moral norms to justify their actions.

Aristotle’s Organon comprises six key essays on logic, initially collected by Theophrastus, his successor as head of the Peripatetic school, and given its final form by Andronicus some three centuries later. The six essays are: Categories, On Interpretation, Prior Analytics, Posterior Analytics, Topics and On Sophistical Refutations. One of the principal topics of Aristotle’s focus is syllogism, in which two premises (one major, one minor) lead to a conclusion. This features in Prior Analytics and On Interpretation.
