 Edwards' arguments for idealism are similar to (but apparently uninfluenced by) Berkeley's. One of the best examples occurs in “The Mind,” no. 27. Edwards first argues that the idea of a body can be resolved into ideas of color and resistance. Figure, for example, is the termination of color or resistance. Solidity is resistance, while motion is “the communication of this resistance from space to space.” “Every knowing philosopher” agrees that colors exist only in minds. ‘Resistance’ refers either to instances in which one body resists another or to a power, namely, a body's disposition to resist other bodies. The first is a mode or property of ideas; it is ideas which are “resisted…move and stop, and rebound.” For example, our observation of a billiard ball's ricocheting from the cushion can be resolved into impressions of a particular configuration of color and figure (the billiard ball) moving closer to another (the cushion), touching it, and then moving away from it. The power of resistance is no more than a divine “establishment,” namely, “the constant law or method” of “the actual exertion of God's power” producing instances of resistance. So instances of resistance are qualities of ideas and the power of resistance is a stable divine intention to act in certain ways. Resistance, therefore, exists only in relation to minds. Since the idea of a body can be reduced to ideas of color and resistance, and color and resistance have only mental existence, “the world is…an ideal one” (Edwards 1957–, vol. 6, 350–51).
