With increasing x, y is shifted toward c. With an increase in x, y shifts toward c. My professor has told me the difference between those is about to have agent or not. But, I am so confused
I suppose he means that "y is shifted" implies that there is an agent causing the shift. Whereas "y shifts toward c" implies that y performs the shift under its own power. But I disagree. In both sentences, it can be said that the increase in x is the agent that causes the shift in y.
Great. Thank you so much. I agree with you. Nevertheless, what about the following? Y shifts towards c. Y is shifted towards c.
Shifting of Y predicates an agent of change even if indirect. Without it Y will stay put. In certain schools of Indian Philosophy, it is called IMPLICATION.
