We live in a physical world, and we can determine physical things, but there is a greater truth that is out there. Now, Locke's conclusions, he realized that they were going to come up against arguments, and people would say, well, you know, and I'm down with this paragraph now, he's going to use the Rene Descartes argument for why he thinks we can have reliability in our sensual perception, because he knows people are going to say, well, yeah, Locke, our senses can be fooled all over the place, we already proved that, but he's saying, well, I'm going to take the Rene Descartes approach to this, because Rene Descartes was the one, and he lived just before Locke did, and he said, that, well, yeah, there might be, this world might be an entire illusion, there might be a cosmic deceiver out there, a cosmic joker, who is simply providing illusions that we think are reality in our world, and Descartes was reduced to the point where he said, you know what, I'm not sure what I can tell right now, but I know I have my intellect, I know I have cognitive thinking, and he said, I think therefore I am, and he got down to that basic building block, and that was the building block last time I said, oh, wow, that's really deep, you know, well, Locke kind of does the same thing, because he says, okay, if you say we are having sensations within us, that we can feel things, we can touch things, we can taste things, even if our senses are fooled, even if the things are an illusion, he says, the fact that I can have those sensations at all means there must be something that stimulates those sensations, which means that there must be an external reality that is stimulated, even if I can't detect if that's an illusion right now, but that our senses are triggered by something tells us that there is a reality out there, and now, the real thing is, okay, you say that, but what about the Matrix movies, what about those Matrix movies, well, that's right, we're going to take a pill, which pill are we taking, I don't remember, which one was it, red pill is reality, the other one you're living in a fantasy world, now, the people, right, the people were living in a, now, some people may not have seen the movies, okay, Bill's like, oh, my gosh, what are you talking about, I've read the film, what are you talking about, the people were locked away by the machines that were in control, and the machines were stimulating the senses of the people who were under control, they were kept in these little pods, but they didn't know it, they felt like they were out walking the streets every day, right, seeing their neighbors, waving high, driving cars, that all those things were experiences that were put inside their mind and in their brain by the machines that figured out that they could stimulate, you know, the electronic impulses of our minds, and we're kind of back to the same argument again, it's like, well, how do we know we are not cosmically deceived, we're kind of almost in the Rene Descartes argument again, is there a pill we can take that will illuminate us, the Bible, because that's the thing, well, we're going to get there, but right now, I just want to talk about truth itself, is there a way to determine if there is truth, now, remember also, we talked last time, and I'm going to scroll down here, remember we talked about Plato's cave, Plato's cave was a situation where people were locked away and they could not see the light of day, the only thing they could see in that cave was a projection of light from behind them, they would look forward and they would see shadows of trees or bushes or animals, whatever it was, and for them, that was their reality, they did not know anything else, that's all they knew about, and one day, somebody escaped from that cave, and they experienced the light of day, and they realized there was a whole nother reality that they did not know about, and this is the argument here, that even if there is a grand illusion, even if there is something out there that is preventing us from knowing things, you know, to the fullest extent, even in these situations, it wasn't that there wasn't reality, it was that they had limited experience and knowledge of that reality, for, what is it, Nilo, or Nilo, Nio, in the Matrix movies, his illumination was taking the red pill, and once he took that red pill, he found out there was a whole nother reality he did not know about or understand, for the prisoner in the cave, it was coming out to the light of day and seeing things that he had never seen before, and now understanding that there were bigger and greater things, the question is, is there something that illuminates us, where we can know reality?
