Sir 17:1

“"God created man from the earth," namely as regards the body, "and made him according to His own image," namely as regards the soul. He gives us to understand that the human soul has three operations, according to its power and operation. "Every noble soul has three operations," by which it turns itself upon its own body, upon itself, and toward divine things. Sometimes it turns itself upon the body: it has the tongue for speaking, ears for hearing; sometimes it turns itself upon itself; sometimes toward understanding and knowing God. And this is according to the threefold consideration of the soul; for the soul is considered as the form and perfection of the body, as a this-something, and as an image.”
