"We shall not cease from exploration
And the end of all our exploring
Will be to arrive where we started
And know the place for the first time."

Between a Rock and a Hard Place

A particularly philosophical friend of mine and I had a similar train of thought a few weeks ago concerning personal ethics and freedom. She approached it via deterministic self-knowledge, whereas I was looking at it from the tiresome old question of purpose in life. I will use her case as the departure point as it is more general, though I think not explicit on a few points that I was thinking about.
"Knowing who you are means you have a good idea what you're going to do next. Perfect self-knowledge means you can predict precisely what you'll do in response to any situation. But that's equivalent to knowing your future. And knowing your future means giving up free will, because you can see every choice you're going to make." 
~Elizabeth Marston (via Facebook)
Free Will versus Meaning
Self-knowledge thus negatively correlates with phenomenological free will. This holds true for and deterministic vector, including purpose in life. If there is an intrinsic purpose in life, then it functions as a goal for your actions – that is if you are aware of it. If you were to know your purpose in life (if there is one), you would have a fantastic amount of self-knowledge. You would have, in effect, a blueprint for every nontrivial action (which would also incidentally solve most – if not all – issues of personal ethics). The downside of this is that this blueprint reduces you to a slave to your purpose. You becomes an automaton, devoid of [the experience of] free will.

On the other end of the spectrum, having zero self-knowledge causes the problem of being a wild animal, slave to your most base drives, with no way of self-checking. Ethics –personal or otherwise – are not even on your radar. At this hypothetical extreme, memory isn't possible as it is a form of self-knowledge. You are again a mere automaton. Furthermore, you gain an intrinsic purpose: to follow your drives. Les extrémités se touchent, as the French say.

While free will may be a de facto illusion, clearly we do experience free will within the limits of a mixed strategy. The question of where we achieve the optimum output of free will I do not think can ever be definitively answered, and certainly not within the scope of this blog.

Free and Meaningful Tug-of-War
Is free will an important thing? As roughly meaning autonomy and agency, we certainly do seem to value it culturally, though this was not always so. It is not an imperative, though purpose (meaning) is. It could be said that meaning is a prerequisite to free will, as without it you are unable to act (you are without direction, without the ability to evaluate), hence a mixed strategy being optimal as far as free will is concerned. The only way for this to happen requires imperfect or incomplete ("flawed") purposes, meanings or models.

Again we are brought back to the problem of what we should value. We have conceived several times here of pure systems that fully lack phenomenological free will, which incidentally may be more honest if we are to assume determinism to be true. As I've noted elsewhere, the act of the gears turning is experienced as conscious free will, and we as thinking beings cannot escape it either.

So here we are, stuck between two extremes. Finding optimization of whatever ratio of free will and meaning that we feel is right, though no one solution will ever satisfy the problem completely. This is another facet of the human condition. By our very nature, we cannot ever completely win. But perhaps that isn't either here nor there. Perhaps this need is what keeps us going, searching, thinking, acting. We have an action potential that cannot ever be fully discharged until death takes us. We could still achieve all that we do without this, as machines and computers, but – I think – this is the difference of what makes us human.

"He who despairs of the human condition is a coward, but he who has hope for it is a fool." 
~Albert Camus 
Outline

  1. Complete free will requires the absence of intrinsic purpose, and vice versa
  2. Purpose is approximately equal to meaning, and thus value
    • We need values in order to evaluate
    • We need to be able to evaluate against some model in order to act
      • Purpose is a prerequisite to action, and this free will
        • A mixed strategy is required in order for free will to operate
  3. We are thinking creatures, and experience "the gears turning" as free will
    • We cannot escape free will or the need for meaning
