Unfortunately PoR I cannot agree with your views. For the most part because of lack of logical proof. What you have given the forum is not an argument but rather a serious of conclusions that have no premises. Without the proofs, unfortunately, your conclusions have little to no truth value. Also, a few of your points I have objections to (as others in the forum has mentioned as well).
Conclusion one makes me wonder about morality and those things that are outside of mechanics. If the mind is nothing more than brain, our existence stops with death. However, it is now being theorized by scientists that it may be able to download our consciousness into a computer and guaranteeing imortality of thought.
I can agree that it seems as though time is a construct of human thought and understanding. However, the idea that the universe has only three dimensions is unwarrented. This is because we know so little of it. There seems to be a way out of this by ammending your statement to “The universe must have AT LEAST Three dimensions.”
The third conclusion is one that makes me extremely nervous. If our thoughts are just our invention there is a problem. This is because we are only privy to our thoughts. Even our perception of the outside world is nothing but what is seen in our head. We cannot step outside of ourselves and check to be sure what we are perceiving is accurate. Because of this we cannot also be certain that we are perceiving the world in at least a representative form. With that being said, it is not hard to imagine that what we view in our head is not what is actually in the external world. Then our physical perceptions are broken down to nothing more than a thought as well (which established by you is our own invention). Therefore, we invent everything. This conclusion leads us into solopcism.
Also, you have a problem with consistancy between the fifth and first statements. If what governs us is beyond rationality then there must be something beyond physical bodies.
As another poster mention, it would help if you would define meaning. It can also be said if you prove your first statement then this one is a bit superfulous. This statement is contained in your first if it is true that we are nothing more than another animal.
Finally, if a persons thoughts are only their own inventions that means that a man is justified in believing anything he can think. This tells us nothing about truth or wisdom and discredits every field of study from science to economical studies, because a man can believe what he can imagine.
Feel free to disagree with any of these points, but I feel that this view is flawed. But don’t cut down PoR for only having seven points to a philosophical system. Descartes only had Three in the Meditations. Perhaps PoR was applying Ockam’s Razor?
