It would be anachronistic to suppose that Locke is using the word “determine” as we do today when we discuss causal determinism (see the entry on    causal determinism). And the desire to avoid anachronism might lead us to adopt the teleological interpretation of determination. But there are many indications in E2–5 II.xxi that Locke has something approaching the causal interpretation in mind. Locke’s picture of bodies, both large and small, is largely a mechanistic one (though he allows for phenomena that can’t be explained mechanistically, such as gravitation, cohesion of body parts, and magnetism): bodies, he writes, “knock, impell, and resist one another,…and that is all they can do” (E1–5 IV.x.10: 624). And there are indications that this mechanistic model of corporeal behavior affects Locke’s model of mental phenomena. Throughout the Sections of II.xxi added in E2–5, Locke talks of uneasiness moving the mind (E2–5 II.xxi.29: 249; E2–5 II.xxi.43–44: 260), setting us upon a change of state or action or work (E2–5 II.xxi.29: 249; E2–5 II.xxi.31: 251; E2–5 II.xxi.37: 255; E2–5 II.xxi.44: 260), working on the mind (E2–5 II.xxi.29: 249; E2–5 II.xxi.33: 252), exerting pressure (E2–5 II.xxi.32: 251; E2–5 II.xxi.45: 262), driving us (E2–5 II.xxi.34: 252; E2–5 II.xxi.35: 253), pushing us (E2–5 II.xxi.34: 252), operating on the will, sometimes forcibly (E2–5 II.xxi.36: 254; E2–5 II.xxi.37: 255; E2–5 II.xxi.57: 271), laying hold on the will (E2–5 II.xxi.38: 256), influencing the will (E2–5 II.xxi.38: 256; E2–5 II.xxi.39: 257), taking the will (E2–5 II.xxi.45: 262), spurring to action (E2–5 II.xxi.40: 258), carrying us into action (E2–5 II.xxi.53: 268), and being counterbalanced by other mental states (E2–5 II.xxi.57: 272; E2–5 II.xxi.65: 277). It is difficult to read all of these statements without thinking that Locke thinks of uneasiness as exerting not merely a pull, but also a push, on the mind.
