Senses are the closest to Truth

We've been talking about senses for a while now. I admit that our senses are not perfect, but I do not agree with people who claim that we know nothing. We might not know everything, but we do know ALOT! Just because things like illusion and hallucination occur, doesn't mean that we don't know anything. Just because we got one math problem wrong, doesn't mean we don't know math at all. Illusion happens very rare compare to our normal perceptions. Most of the time, we won't call a cow a horse. Also, we have many (5,6?) senses for a reason! During Ali's group's presentation, we listened to some different sounds, and people made different guesses. Even though our ears did not tell us exactly what those things are, in reality, our eyes will tell us. When i hear something ringing, i might not know what it is, but if i follow the noise, I'll find out if it's the alarm or cell phone. We can also train our senses. We might not be able to smell our way home like salmons; we might not be able to see the floor from the sky like eagles. But that doesn't matter. Human and animals and plants evolve to adapt to the environment. We can't do certain things because we don't need to. We don't have to use our nose to get home, we can remember it. We don't have to see from that high, we can use a telescope. If we really need to, then just like a professional tea taster, we can train our senses and maybe evolve. And who cares if we are only brains in a laboratory? What we see, smell, taste, feel and hear are the only reality for us. I understand there are people who are (for example) color blind. How do we know if that's not what reality is? Maybe they are the only normal ones and the rest are all color blinded. But it doesn't matter! The society depends on the majority of people. If all people say it's red, then it's red! It's like a vote. If everyone vote for Roger, but Jon is (in reality) a much better person. We can't just screw everyone else and make Jon the president!

You make a very good point about using our senses in combination. This is a good example of how to strengthen one weaker way of knowing. If it is unclear what is making the sound, we use our eyes as well to determine if it is an alarm clock or a cell phone. Excellent point and excellent illustration of what we are looking for.

I would be surprised, however, if some people did not want to challenge the ideas that it does not matter if we are just brains in a laboratory and that reality is somehow determined by majority vote. While it is true that in a democracy the majority may vote Roger to be president, can the majority make something red if it is green? Is the majority right in the area of ethics if it is says one group of people should serve another?

As I understand your final point, you're not saying that majority dictates reality, but rather that the majority dictates what we (as a society) accept as reality. Because most people see color and fewer people are colorblind, we treat perception in color as closer to reality than we do colorblindness.
But when we use objective measurements that aren't colored (as much) by human imperfections [ for example, differentiating between colors by measuring wavelengths rather than asking people whether two colors are the same], we can overturn the majority. Our respect for knowledge through objective experimentation is what tells us (or in this case confirms for us) that things do have different color and that those who see color perceive more accurately than those who don't.
