Final answer:
Aristotle's approach to ethics did not provide a philosophical argument against slavery.
Step-by-step explanation:
The statement that Aristotle's approach to ethics provided a philosophical argument against slavery is false. Aristotle did not argue against slavery in his ethics. In fact, Aristotle believed that there were natural slaves who were meant to be enslaved by their natural masters. His ethical theories focused on virtues and the pursuit of the good life, but they did not address the issue of slavery.
