Analyzing the Highest and Worst Moral Attributes from the Perspective of Aristotle, Aquinas, and Khajeh Nasir-al-Din Tusi.

Aristotle, Aquinas, and Khajeh Nasir al-Din Tusi are representatives of the three periods and the worlds of thought, and all of them have played an important role in establishing or consolidating their ethical attitudes. In this essay, it was attempted to identify and analyze the highest virtues and the worst ethical vices from the perspective of each of these three wise and expert philosophers. For Aristotle, the highest virtue is justice and greed and the worst vice is oppression to friends. For Aquinas considers Caritas as the highest virtue of and the worst vice is the disappointment. Khajeh Naseer regards grace as the supreme ethical attribute and stinging as the worst, although envy and anger can also be considered as the worst vice in a rather vague interpretation. Comparing the results of the work, firstly, suggests that the views of Khajeh Nasir and Aquinas are close to each other, and secondly, Aristotle's has more sophisticated view to ethics and ethical virtues than two other thinkers.
