We speak of a "state of mind" as naturally as we speak of a "change of heart". A thought is essentially a state of mind, just as feelings emerge from our changes of heart.
We may say that thinking (an act) changes our state of mind. Conversely (pangrammatically), we can say that a feeling (a fact) "states" a change of heart, i.e., it registers it. We notice our changes of heart by feeling. We trouble our state of mind by thinking.
Philosophy is conceptual notation; it takes note of our states of mind in order to bring our concepts to presence. This helps us think better.
Poetry is emotional notation; it notes our changes of heart and brings our emotions to presence. This helps us feel better.
