The internal senses are powers of man’s rational soul, they are located in no particular place within the body. That is because the rational soul is immaterial in nature as a result the powers themselves are immaterial, they cannot be measured empirically. These powers work in harmony with the external senses. The four internal senses are a product of cause and effect. The existence of a effect can lead us to seek it’s effect. We discover the nature of a cause “by studying the effects that proceed from it.” The four internal senses are the common sense, the common sense, the imagination, sense memory, and the cogitative sense. The internal senses require a bit more fleshing out.
Keep Praying for me. I pray for each of you daily!
