No, it isn't. The Force is no more utilitarian in the PT than it is in the OT. As Obi-Wan says, it partially controls your actions, but it obeys your commands. The Force is also no more externalized in the PT than it is in the OT. In the OT it is described as an energy field created by all living things which surrounds us, penetrates us, and binds the galaxy together. You'd be hard pressed to argue that the Force is not externalized based on either that description or the similar one in TESB, which insists that the Force is between the rock and the X-wing. The "strong implication" that you apparently picked up - that Force use is generally available to anyone through training - is supported nowhere in the OT. In fact, the often forgotten ROTJ argues against it, and shows Force potential being genetically inherited in a family bloodline. Also known as "governed through a genetic anomaly". No, it isn't. It can't be, because as previously stated, Yoda does not "present the Force" in the PT. Thus his presentation in the OT stands because there is nothing in the PT to diverge from it. What Yoda does say in the PT is entirely consistent with the OT. As one example, what he says to Anakin in ROTS reflects what he calls the "way of the Force" in ROTJ. As another, what he says about the dark side in TPM is essentially the same as what Obi-Wan says about it in TESB.
