Abstract
We present a thesis which has a negative implication to the power theory of Ehara. We examine the significance of the thesis. First, we define “existence of power” by amplifying Ehara's discussion. We formalize “willing choice” in her theory. Secondly, we demonstrate impossibility of escape from “Power” defined by Ehara, by invoking Sen's “liberal paradox.” We guess that Sen's condition “unlimitation of preference” is not really satisfied and that the limitation of preference is related to “context”. Finally, we cast a about on “power” theory approaches in feminism.
