Bonaventure & “Affective Experience”

In Bonaventure’s _The Soul’s Journey into God_, the Seraphic Doctor offers a regimen for how the soul can come to mirror God, a suggested path for what this might look like.

In this context he says that such an achievement “is more a matter of affective experience [of the inner senses] than rational consideration.”

What might this affective experience of the inner senses mean? What is “inner sense,” anyway?

Without getting too bogged down in pre-modern faculty theory, recall that Aristotle and his medieval followers believed in a faculty of the soul called the “common sense.” This faculty or power is what allows a person to coordinate various sensory input. For example, consider an ice cube. If one holds the ice cube in her hand, she perceives by the sense of touch that it is cold, but she _also_ perceives by vision that it is grey in color, and cubical in shape. But how does she know that the cold thing and the cubical thing are one and the same thing? She knows this, thanks to the work of the inner sense power called the common sense.

Now, although for some early modern thinkers such as Descartes the common sense receives its input prior to the work of the memory and the imagination, for scholastic thinkers such as Thomas and Bonaventure, the common sense is situated _after_ the memory and the imagination. What this means is that the work of his faculty is not limited to the coordination of various sense stimuli, coming from diverse organs of the outer sense (e.g. eyes and skin). Rather, the common sense also imbues the object of thought with qualities supplied by memory and imagination. Surely it is here, in the memory and the imagination, where the “affections” which Bonaventure stresses, originate.

I thought of an example. Suppose you had a bit too much to drink last night. Suppose you drank a bit too much vodka, and you are a bit hung over. Suppose, further, that you just finished a 7 mile morning run, and you are very thirsty. You look up and you see two bottles, both containing clear liquid. For the purpose of this analogy assume that neither bottle has a label on it. You know that one bottle contains vodka, and the other one water.

Notice that the sensory input coming from you eyes as they gaze upon the different bottles is identical. That is, the eyes perceive no difference between the liquid contained in the two bottles: in both cases it is clear and colorless. Yet when you focus on the bottle of vodka you are repulsed, and when you focus on the bottle of water, you are so attracted to it that your mouth waters, impelling you finally to pick up the bottle, open the lid, and gulp down its contents.

What accounts for the difference between your different perceptions of the two bottles of clear, colorless liquid? It is not your vision or any other external sense power. The difference is “affective:” your perception is altered by the “inner sense power,” the “faculty” of “common sense,” which combines features of the two liquids, supplied by the memory and the imagination, with your visual perception of them.
