Can you quickly define what exactly you mean by subjective, in this case? Under my understanding of the term, there is nothing subjective about the result that occurs when two physical objects interact. The event simply happens, and what results, results. The fact that, with the events we’re talking about now (perception), these events produce information in our brain does not make perception an exception to the general rule, any more than computer programs which produce informational results are thus exempted from causality. It is the direct causal connections involved in the process of perception which makes the results reliable. The light currently hitting my eyes could not, in principle, produce any perception other than the one it is currently producing.
Paticular to a given person. Sorry, should make it clear when I use a word with different definitions like that.
Uh… I’m assuming that you don’t mean physically reconstruct, but rather in our minds?
Either/or in the context of this conversation.
The whole point of this conversation is that when we look at a sewing machine, the perception which results isn’t one that we had to reconstruct; it happened automatically.
No, the whole point is not whether it is volitional or not, but whether it is accurate. Whtether it is true representative information of objective reality.
Now, this is not to say that we observe even the “most absolute details” of the sewing machine. No one here is claiming that we have x-ray vision sufficient to perceive the inner workings of the machine just by looking at it, or that we can perceive each of the atoms exactly. This is not what we mean by perfect. When we say perfect, we do not mean that all information which could ever possibly be gleaned is immediately apparent. If this were true, we would not need microscopes, telescopes, or hearing aids. Rather, when we say perfect, we mean that none of the information that we actually do get is false.
This is what I have a problem with. How is it true information when we are not perceiving it, or even anything about it totally?
Perception cannot deceive any more than a scientific experiment can lie. There can of course be some unseen factor operating in a scientific experiment, which if we do not know, we can draw bad conclusions about. However, the outcome of the experiment itself cannot defy reality. There is no room for deviation in the automatic workings of our central nervous system. We can draw false conclusions and inferences from the information we get, but everything that perception gives us is connected to the object itself by inerrant laws.
Connected, but that does not necessarily imply truth.
Again, I think we are operating under different definitions of imperfect. The information I get from perceiving a tree from 50 feet away is certainly not exhaustive; I could get much more information from perceiving it closer up, from different angles, perhaps by including different senses such as touch, sound, and taste. In this sense, it does not give us a perfect idea of everything that a tree is or possibly could be. However, to the extent that it does give us information, this information must be true. It is in this sense that it is perfect; how could mechanistic operations be otherwise, in this sense?
Our perceptions are what they are, they cannot deviate. The events that allow us to perceive what we do are the same. I don’t see how you get from this that what we perceive is true.
I’m not convinced that this is a valid question to ask concerning the existence of free will. Moments in reality, after all, never do repeat themselves. How can our concept of free will thus be based on an impossible occurrence?
Because this impossible situation is what free will entails. Thats the entire idea of it. Its what free will is.
