Final answer:
Aristotle's concept of the soul includes the vegetative soul for plants, the sensitive soul for animals, and the rational soul for humans, which combines intuitive reason and scientific knowledge.
Step-by-step explanation:
When considering which of the following states of the soul is a combination of intuitive reason and scientific knowledge, one should refer to Aristotle's accounts of the soul. Aristotle believed that all living beings possessed souls differentiated by their abilities. For plants, it is the vegetative soul occupied with growth and nutrient exchange. Animals have the sensitive soul, which adds the ability to desire and move. Finally, humans possess the rational soul, unique in its capacity for intuitive reason and scientific knowledge, enabling the body to perform all functions a lower-level animal can and also carry out rational thought.
