We've just gotten to Descarte in my Philosophy class.
I now understand how doubt can be applied to anything but thinking,
the old "I think therefore I am."
I also understand that perception of reality go through your senses, but the validity of your senses can be doubted.
My teacher says that Descarte goes through 6 or 7 meditation to build a foundation of unshakable knowledge/truth. If I recall what my teacher said at the end of class; Descarte will prove that our surroundings are real and that our senses are not being manipulated so...
If How does one perceive reality without doubt?

I see now, it is not so much on how to prove the senses exist but to use the skeptics own doubt against them.
How do you know you are being lied to if the deception never failed.
If you believe that your senses can be false then you are basing the lie on an event in where the your senses were true.

Ah, this debate. I'm a solipsist at heart, so I take cogito ergo sum to its logical extension: I think, therefore I, but I don't know about anyone else, so I don't think they are. The world is based off of my mind and its creations.
In answer to the question of how do I know if I'm being lied to...? The answer is: I don't. This could be real. For me, I suppose, it must be real, since my perception of reality is based off of my experiences. This is all I know to exist. But I also believe that since this is all in my mind, I can change things and/or have already changed things (which I think explains my wonderfully faulty memory).
As for perceiving reality without doubt... I just don't know about the rest of it. My reality is fairly alright for me, but the rest of reality... don't know.

Sorry, I haven't updated, since the guild has experianced a lull.
But to know that your senses are being deceived you would be saying at one point they were not being deceived. You can only know you are being lied to when you compare it to the truth. If this is true, which is the only truth we know, then the senses are not lying to us.
