Abstract
St. Thomas did not bring out any question on beauty in his Summa Theologicae. All the questions in it are devoted to considerations of God ; the sacred science which teaches us the knowledge of God. He does not express God by the term "beauty", distinguishing it from goodness in "ratio"-namely, not in its logic, but in its causality. Beauty has the "ratio" of formal cause which is the same intrinsic principle as material cause and doe not extend to anything but those which are actual. Beauty relates to the sensibility of the eye as an organ of a certain cognitive ability. The sense of sight, however, cannot be raised up to anything immaterial, being altogether material. We, therefore, cannot explain God in terms of beauty, but it doesn't necessarily mean that we cannot discuss the problem of the transcendence and the value of beauty, when we pay attention to the parallel relation between sight and intellect, that is, the hylemorphological way of construction of form.
