Comparison
Virtue Ethics vs Deontology
Should ethics start from the character of a good person, or from the rules a right action follows?
Virtue ethics
From character. The right act is the one a person of practical wisdom, acting from virtue, would perform.

From rules. Right action is fixed by duties and constraints that hold whatever one's character.
Read the full entry ›What both accept
Both reject the idea that consequences are all that matter, both think ethics is a subject reason can address, and both take seriously that a moral life is more than following whims.
Where they decisively part
Virtue ethics makes character primary: the right act is what a person of practical wisdom would do, and rules are at best rough summaries of that judgment. Deontology makes the rule primary: right action is defined by duties and constraints that hold prior to, and independently of, any judgment about character.
The strongest case for each
Virtue ethics
It captures that ethics is lived, not just decided: it explains moral development, the role of emotion and perception, and why the same act can be admirable or hollow depending on the person and motive behind it.
Deontology
It gives clear, public constraints that protect people regardless of anyone's virtue or motive, and does not depend on first agreeing about what a flourishing human life is.
The strongest objection to each
Virtue ethics
It can seem to offer little concrete guidance in a genuine dilemma ('do what the virtuous person would do' assumes you already can), and it leans on a contested account of human flourishing.
Deontology
Rules abstracted from judgment can misfire in cases they did not anticipate, and a focus on duty can miss that the same dutiful act can express either genuine goodness or cold rule-following.
When they predict differently
They diverge in hard cases with no clean rule, where virtue ethics trusts cultivated judgment and deontology looks for the governing principle, and in how they treat moral learning: habituation of character versus grasp of the moral law.
