Final answer:
The statement regarding Plato's emphasis on the four cardinal virtues: wisdom, courage, temperance, and justice is true and they form a central component of his philosophy as presented in 'The Republic'.
Step-by-step explanation:
A statement that Plato emphasized four virtues in particular, which were later called cardinal virtues: wisdom, courage, temperance, and justice, is indeed true. This conception of virtues is central to Plato's philosophy regarding the ideal state and individual conduct, as articulated in his work The Republic. In this work, he describes the virtues necessary for the parts of the soul and the classes within the state to function in harmony, ultimately leading to a just society. Such virtues also play an important role in the individual's pursuit of the good life, as a balanced soul reflects these virtues.
