Re: Who- why- where are we ?

I beg to differ. If I haven't convinced you, try putting 'not knowing if something is or isn't the case' into a piece of formal logic. There you go: http://cas2.umkc.edu/philosophy/vade-mecum/3-1.htm The name for the formula "it is not the case that..." is negation. I think you may be unc...

Re: Who- why- where are we ?

We don't know who shot John F. Kennedy. Therefore, the case remains open. Yanomami people don't know cars exist. Therefore, they find no use in gasoline. Philosophers don't know noumena exists. Therefore, they cannot proclaim its existence. I don't know that my senses are reliable. Therefore, I mus...

Re: Who- why- where are we ?

Conda Lucanor wrote: I disagree, since I think (as many others in the history of philosophy) that the Theory of Form advances a theory of existence, specifically the existence of universals opposed to the existence of concrete singulars. The key to our disagreement here is the word 'existence'. Can...

Re: Who- why- where are we ?

Because Descartes starts off by doubting the evidence of his senses, that means that he must start his philosophy from somewhere else i.e. cogito... If you cannot assign a truth value to a proposition then you can't do logic with it. We don't know who shot John F. Kennedy. Therefore, the case remai...

Re: Who- why- where are we ?

My too brief account of theories of existence misses several important theories , but Plato advances no theory of existence at all: Plato advances a theory of a hierarchy of truth. I disagree, since I think (as many others in the history of philosophy) that the Theory of Form advances a theory of e...

Re: Who- why- where are we ?

It is difficult to respond if you quote my posts one sentence at a time and give one sentence responses. If I do the same it makes it unintelligible to anyone else and it also means we tend to wander away from the point. That's why I'm not going to respond line by line. And I've said all I have to ...

Re: Who- why- where are we ?

There are no logical consequences to saying you can't know something. You only start doing logic once you have made an assumption that something is either true (or false). That's simply not true. And of course there are logical consequences to saying you can't know something. Didn't Descartes start...

Re: Who- why- where are we ?

Conde Lucanor, you see some model for existence theories which I don't see. I wish I did understand what model of existence theories your thoughts append to. You wrote: Going back to the car analogy, a materialist won't believe that an immaterial substance, namely the car's soul or mind, is what ma...

Re: Who- why- where are we ?

you don't agree that to be a materialist you need to account in some way for mind, even if you say it's nothing but an epiphenomenon. And, you cannot be both a substance dualist and a materialist at the same time, they just don't fit together Materialism is monistic and will not acknowledge any sub...

Re: Who- why- where are we ?

We can sum up this to 3 options. Either: 1) There is a noumenal world behind phenomena. 2) There is not a noumenal world behind phenomena. 3) We cannot know that there is or there isn't a noumenal world behind phenomena. I pick 1. What's your pick? It is not like picking a football team to support....

Re: Refutation of Time Travel

I don't believe in time traveling, but the demonstration is not valid, because the first premise is false. According to the first premise, all I have to do is to claim that I'm a time traveler or that I have seen one to prove that there's time traveling, but stories of time travelers do not imply t...

Re: Who- why- where are we ?

Not necessarily, since when we are describing phenomena we are referring to how the noumena appears to us. In other words, because things as they appear to us are intrinsically related and depend of things in themselves, our perceptions can give us keys to knowing how the world of things in themsel...

Re: Who- why- where are we ?

It's not correct that minds are what physical brains do. What the brain does is the physiology of the anatomical brain. Mind is something else. What the brain does can be looked at by means of scientific instruments, but what we usually mean by the mind cannot be looked at by scientific instruments...
