Sensible realities are those which are perceived by the five outer senses: So, for example, those outward things which the eye sees are called sensible. Intelligible realities are those which have no outward existence but are perceived by the mind. For example, the mind itself is an intelligible reality and has no outward existence. Likewise, all human virtues and attributes have an intelligible rather than a sensible existence; that is, they are realities that are perceived by the mind and not by the senses (74:2)
