rlumley, I don't accept that definition of reality. I'm no relativist and I believe in the power of science to discover applicable information about our phenomenal reality, but reality is not what "normal" people see. Reality doesn't depend on people at all. Reality is what lies beyond our perception, but is interpreted by our perception... and this is where you may be deceived. You're blowing my words out of proportion. I'm not suggesting any sort of Descartes evil genie here... I'm just saying that it can help you see the extent to which not just your senses, but your very logic and reason, can be deceived. This is not to say at all that you are being deceived or to what extent, it is simply the possibility. But here is where you actually are wrong... our minds are deceived quite often and it's important to know this.
All your faculties of sense, reason, and logic have been built up for evolutionary purposes, and for most uses, especially those that more intimately govern our survival, they do a pretty good job. But, you have to remember that our minds were built to keep us alive and to reproduce successfully, they were not built with the pursuit of truth in mind. You mention physics as evidence of laws that cannot deceive us, but I actually will have to invoke relativity because it's important to note that most Newtonian physics represents only an approximation, albeit a very useful and applicable one. Neuroscience, psychology, and anthropology have shown that humans have an innate sense of physics, but it is one based on a simplistic model of impulse, not even as complex as Newtonian physics. Initial studies in physics all spend time trying to get students to unlearn their intuitive sense of physics by convincing them that a heavy object and a light object will fall at the same speed if air resistance can be neglected and that an object in motion will stay in motion unless acted upon by an external force. And this is the simplest physics and you're already being deceived by your rudimentary evolutionarily built sense of physics. Electromagnetism, relativity, and quantum mechanics all go much farther and the difficulty we have in understanding these phenomena is very much related to the distance from what comes intuitively. Quantum mechanics often seems to violate our classical logic in many cases.
If you take a short look at some neurological disorders, it's quite apparent how easy it is to be deceived and to deny reality. Just a simple change in your brain can make you absolutely convinced your leg is not your own, or cause you to completely neglect the left side of your vision. Yes, you probably don't have any neurological disorders but all of us are affected to a certain extent by neurological biases which operate on a subconscious basis even before your operant logic comes into play. You don't have to be synesthetic to have a certain degree of synesthesia. This is how you can make abstractions and metaphors and know instinctually that a sharp jagged shape is the letter of a sound like Kee, and a bulbous round shape is the letter of the sound Boo. Most people have an innate bias to look at faces, and more specifically to the right side of the person's face (your left), and more specifically at their right eye. This effect can manifest when you're putting on make up or shaving in the mirror. You have a tendency to look at the right side of your reflection's face, which corresponds to the left of your face. You will naturally spend more time and care grooming your left side as a consequence. But when other people look at you, or you look at a picture of yourself, you spend more time looking at the right side of your face, the opposite of the one you spent more time grooming. That's why you usually look better in the mirror than in a picture, and you might think you look better than other people think you do. This is just an example, but there are neurological biases that go far beyond simple sense bias, and encroach on your fortress of logic and reason.
It's not about thinking there's another reality and that we are being deceived. It's about knowing the extent to which we can be deceived to the extent our assumptions may dominate our logic. I believe more in science than I do in our intuitive sense of logic.
