The answer is: Aquinas believed that all knowledge was based on sensory experience.
According Aquinas. throughout the years, people will utilize our sense of sight, hearing, taste, touch, and smell to acquire as much information as we can.
This process happen when we observe other people's behavior or every objects that lay around at our disposal. After the observation, we store the information into our memory and store it as 'knowledge' that we might use in the future.
