Can you prove that your senses are reliable?

I've been philosophizing quite a bit lately, so I have a question for you all.

Can you prove that the world you perceive through your senses (sight, touch, hearing, taste, etc) is real and that your senses don't actually deceive you?

Note that to do this, you could not references anything external to you (books, people, etc.) because your knowledge of them is dependent on your senses.

So is there a logical argument to prove that the world you perceive is real?

This is mainly for fun, by the way.

    It is impossible to prove that our senses convey to us information about the real world rather than that we are for example a brain in a vat being fed all that information by an evil scientist because any possible proof would be using the very thing in question, our senses.

    However, although we cannot strictly prove that we are not so deceived we have no reason for thinking we are.

    It is illogical and even Aristotle saw through it.

    Proof is ALWAYS secondary, direct experience is unmediated. It is the First Principle for all Proof !! So you are asking for a self-evident Truth to be proved by a derivative proof.

    I ask you --- seeing where your error is -- how can you prove that Logic works ? For on both direct and indirect proof would hang LOGIC itself !!!

    Nothing can be proven.

    so far in my life, my senses have been nearly 100% reliable. i can use my sight to see math problems and solve them and obtain the correct answer, which is the only answer which fits. i can use my hearing to sense when people are talking to me. if i couldn't hear them, then they would get after me later.

    BEFORE diving into a swimming pool, perhaps you dip your toes into the water. If the water is cold, tiny cold receptors in your skin quickly respond. In less than a second, your brain registers the temperature. Pain receptors can transmit information even more quickly. Some nerve impulses reach speeds of 225 miles [360 km] per hour—comparable to running the length of a football field in one second.

    How, though, does the brain work out the intensity of a sensation? One way is by the frequency with which a neuron fires; some fire a thousand or more times a second. The intense activity that takes place among neurons in the brain would be impossible were it not for the work of pumps and powerhouses.

    Each time a neuron fires, atoms with an electrical charge pour into the cell. If these sodium ions, as they are called, are allowed to accumulate, the neuron will gradually lose its ability to fire. How is the problem solved? “Every neuron,” explains science writer Anthony Smith in his book The Mind, “contains about a million pumps—each one is a slight bump on the cell membrane—and every pump can swap about 200 sodium ions for 130 potassium ions every second.” Even when neurons rest, the pumps keep working. Why? To counteract the effect of sodium ions that leak into the cell and potassium ions that leak out.

    The activity of the pumps requires a constant supply of energy. The energy comes from tiny mitochondria, or “powerhouses,” scattered inside each cell. To produce energy, each powerhouse needs oxygen and glucose supplied by the blood. No wonder your brain needs so much blood. “Although it constitutes only about 2 percent of total body weight,” explains Richard Thompson in his book The Brain, it “receives 16 percent of the blood supply . . . Brain tissue receives 10 times as much blood as muscle tissue.”

    The next time you feel the temperature of water, be thankful for the trillions of pumps and powerhouses in your brain. And remember that all this activity is possible because of oxygen and glucose transported by your blood.

    Could something so highly organized and orderly like the hand, the eye, and the brain have come about by chance? If man is credited with inventing tools, computers, and photographic film, surely someone should be honored for making the more versatile hand, eye, and brain. “O Jehovah,” the Bible psalmist said, “I shall laud you because in a fear-inspiring way I am wonderfully made. Your works are wonderful, as my soul is very well aware.”—Psalm 139:1, 14.

    To know anything, you must know everything, or know someone who does. God is all knowing. God reveals things to us in such a way that we can know them for certain. God is the necessary precondition for knowledge, other wise you are left reasoning that your reasoning is valid, and that is viciously circular. When someone says they can be wrong about everything, they can not logiclly KNOW anything, and are reduced to absurdity.While any ultimate authority claim is circular. The difference is, reasoning that your reasoning is valid, is viciously circular (appealing to a fallible source), the Christian worldview is virtuously circular (appealing to THE infallible source).

    No. You can not prove that. In fact, we already know that we don't perceive all of reality. We only see a fraction of light, and only hear a fraction of sound. Same goes for out other senses. We are very limited organisms. Though, we are far less limited than anything that has existed before us.

    I assume that my senses do distort information. It's been well established.

    What you are describing is Descartes Evil Demon Argument. His answer is good "Cogito ergo sum."

    In any case, when faced with the unknown, you need to determine what the rules are. If everytime you open a particular door you find the bathroom, that is a good place to look if you need to go.

    Philosophically it is an interesting question. The best way to determine what is true is via the scientific method, and verification by others.

    If I look into the night sky and the stars spelled out "Daniel - I am the Lord thy God. Repent!" I would look to someone nearby and ask if they see the same thing. If not, I can be reasonably sure I've had a stroke and should visit the hospital.
