Hello, Inquisitor,
Perhaps we could begin by simply asking ourselves what it would mean to suggest that free will exists as a real feature of the external world. It would mean that the nature of objective reality is at least partially defined by the potential for entirely indeterminable causes. This is because we are presupposing that the whole of reality allows the possibility that an unguided agency can exists separate and apart from the ordinary operation of material cause-and-effect, one which has the power to alter the normal course of events. But in order to consistently believe this, one’s understanding of reality would have to be considerably limited, in at least one important sense. Such an idea presupposes that objective reality, as “the whole of all that is,” is ultimately closed to us, since from the free will point of view, external causal factors which could theoretically exert a very real influence on the ordinary operation of material cause-and-effect must always be presumed possible. Otherwise, there is no room for free will.
So long as this is acknowledged by free will advocates, there is no issue with logical consistency. These advocates must simply seek to understand what is meaningful, rather than what is “actually out there.” So long as they pursue “meaningful reality” rather than “objective reality” there is no problem. However, if an understanding of the external world as a whole, one that is purely objective (meaning observer independent) is ever sought by such advocates, then the pursuit of such an understanding would mean that the idea of free will is no longer being presupposed, and that they have replaced a teleological pursuit with an ontological one.
On the other hand, the purely deterministic way of understanding the whole of reality also presents certain problems, and in fact they are the reverse of the one mentioned above. If we ask what it would mean to suggest that the whole of the external world is completely deterministic, we would essentially mean that everything conceivable, including the knowing self, must be a part of a complete whole, the entire operation of which cannot be influenced by external causal factors, for there could be no external causal factors. If any inexplicable outcomes emerge, then the whole of reality is not being considered presently, but rather, an incomplete part is considered instead.
So long as this is what advocates of determinism expect from the idea of “the external world” they investigate, there is still no problem, provided they do not seek to discretely quantify abstract concepts such as consciousness, self, awareness, etc. For once they begin trying to quantify such things, they have essentially taken on an impossible task. They could hardly quantify the very process of quantification itself, since a process is not an object, as conceived, but rather, is a way of seeing or arranging objects. The observer of any phenomenon has to understand himself as some kind of unquantifiable process in order to meaningfully proceed with any goal-directed behavior. The observer has to understand himself as an external causal factor in anything he endeavors to do. So an effort to understand all things deterministically is, knowingly or not, an effort which renders the philosophical pursuit of personal meaning superfluous.
A determinist has two possible ways of seeing this situation, from his own personal perspective: He can attempt to incorporate his personal conception of “self” into his purely deterministic theory of the external world, in which case, he ceases to experience himself as having a meaningful existence. Or alternatively, he can persist in the belief that he is somehow exempt from what the idea of pure determinism actually requires of him, and continue attempting to act meaningfully within a world he is trying to completely reduce to order. But in the case of the latter, he will not truly conceive himself as being part of any such world, and so, he must fail to take account of every aspect of “the whole.”
The contradiction brought about by either of these two perspectives being taken as an absolute and independent description of objective reality lies in the fact that there are some fundamental logical understandings from which any given observer must proceed before it will be possible to approach the idea of “the external world.” If one takes the free-will route, and by this we mean to say that he believes that the external world, in its entirety, is one that allows for free will, then he will be saying that the external world, in its entirety, is one for which there can be influences external to such a world. And then he will not be talking about the entire world at all, but some partial world on which the external influences from a greater external world could act.
On the other hand, if one takes the purely deterministic view of things, then he is conceiving of a kind of external world for which all things are knowable, at least in principle. However, he has to take a very particular kind of view of himself before he can do this consistently, a view that is at odds with the very nature of any meaningful pursuit. He must take a view of himself as a non-actor, as a constant in some cosmic equation. But he will not be able to do this consistently. He has to understand himself as a knowing, choosing entity before any action can be taken whatsoever, yet in so doing, he will have conceptually excluded himself from any purely deterministic analysis.
The reason this paradox persists through time is because most people want to be able to say that whatever the “real” situation is, it has to be the same situation for everyone, independent of personal experience. But the solution to the paradox lies in a willingness to take note of how one’s personal experience is the real situation, at least in a personally meaningful sense. And taking either the free will or the determinism perspective would have a meaningful impact on one’s personal experience.
The free-will perspective allows us to act meaningfully, but cannot take account of all that is, since all that is, would have to include the acting self. But an acting self cannot take a fully deterministic account of its own nature while continuing to engage in meaningful pursuits. The purely deterministic perspective allows us to at least theoretically approach the whole of all that is, but at the expense of no longer being allowed to conceive of ourselves as exceptions to the deterministic rule, meaning that we would not be permitted to understand ourselves as personally unguided influences on other things. The contradiction simply lies in our tendency to flip-flop between these two extremes, since it is unlikely that many of us like the idea of proceeding from either position consistently. If we consistently hold to free-will, then there are certain insurmountable mysteries. If we consistently hold to pure determinism, meaningful action cannot exist.
What is most likely is that many people want to be completely free and meaningful actors personally, yet at the same time, want to quantify the entirety of what they conceive to be the external world, in an effort to amass a reliable collection of knowledge about various cause-and-effect connections, so as to maximize the potential for general success in personal pursuits. Ironically, the goal-directed effort to quantify “all that is” ultimately jeopardizes one’s personal ability to understand himself as a purposeful actor, since in order to be faithful to any such quantifying effort, he would eventually have to get around to quantifying his own acting nature. Yet in conceiving of himself as a meaningful actor, he will not be able to do this.
No purely deterministic system can be consistently conceived as being inherently meaningful, and so an entity conceiving itself as a meaningful actor cannot logically incorporate himself into a deterministic theoretical framework. The idea of meaning emerges as a relationship between an observer and the object of observation. So the perceived meaning of a deterministically conceived system must always come from outside such a system. The meaning is always independent of the system.
If we want to act meaningfully, we must proceed from a view that allows us to have free will. On the other hand, if we want all things to be ultimately reducible to purely mechanistic processes, then we will not be able to proceed from a view that allows us to have free will. The contradiction lies in a deep-rooted desire to personally have both, free will, and a fully quantified external world. The problem lies in one’s conception of “external world.” Such a concept cannot include the idea of the acting self, and exclude the idea of the acting self, at the same time.
