From his high-rise Miami condo, an aspiring photographer sees dark clouds gathering in the distance. He remembers that a thunderstorm had been forecast for the evening. He sets up his camera and tripod on the balcony, checks the battery in his remote control, and waits for lightning.

What do these 4 scenarios have in common? They all involve plans for the future: whether that be in 5 seconds or 18 years or even some unknown, indefinite, period. We all routinely make plans and execute them. Most of the time, our plans succeed. Sometimes they don’t. We often have to adjust our plans to accommodate new circumstances. If our plans involve competition, there’s greater risk of failure because our competitor(s) might out-maneuver us with a better plan.
We’re so inured to plans and planning that we take them for granted. It might well be that almost everything we do involves at least a little foresight; even if we don't normally realize it. What are plans, really? Plans are goal-oriented schemes. We consider the variables involved and extrapolate cause and effect into the future to predict the best strategies to achieve our goals. We can even pursue multiple goals and plans simultaneously. This uniquely human skill is hard wired into all our brains.
The human brain is a mass of neurons and synapses passing electrochemical signals around. It’s the most complex object we know of. Even so, it’s still a natural object and, thus, subject to the laws of nature: not the least of which is causality. Our brains, like everything else, are subject to cause and effect. But we understand causaltiy. Causality is a cascading chain reaction of events. A cause creates an effect, so an effect becomes a cause when it, in turn, affects something else.
One of the causal effects of the human brain is imagination; perhaps the most amazing skill we possess. Creativity is a hallmark of human intelligence because it’s a form of imagination. Planning is also a form of imagination: we imagine future goals and the scenarios to achieve them. Imagination is, by nature, a temporal skill – we don’t imagine what’s actually happening right now – we imagine what could happen, later. (For the purposes of this essay, I’m separating imagination from fantasy, so I won’t discuss imagining the past.) But what about the decisions we make in the present? Aren’t they governed by causality . . . by deterministic factors?
Absolutely. Of course. Everything is determined by causality.
Including our imaginations. Because creativity and planning are causal effects of the brain, they serve a critical role – along with heredity, experience, circumstances, and other causal effects – in determining our decisions.
What is the effect of imagination on our decisions? The effect of imagination, particularly of planning, is to give us a temporal advantage over causality. Our imaginations (figuratively) take us where causality can’t go: the future. When we go to the future, we take our understanding of causality with us and make our best estimate of what we can expect in the future. In other words, we plan. By planning, we will (hopefully) be prepared for causality when it arrives. Plans, in a mental feedback loop, are mixed in with all the other causal factors that determine our decisions; then they exert a unique effect on our lives . . . they select potential futures – and, thus, guide the "causal paths" we take through life. The causal effect of imagination is, literally, self determinism: free will.
This is how free will can exist in a deterministic universe and emerge from causal processes in the brain. To the extent that we actively anticipate causality, free will is a causal effect – a consequence – of our human imagination. Thus, not only is free will compatible with determinism, it's a natural, causal, effect of human imagination. They're not antithetical at all.
When determinism meets human imagination, the effect is self determinism. No hocus pocus: just a
