Descartes defines reality in a very selective way. The things that we take in with our senses are not truly real to his way of thinking, and he instead puts the mind before the body. They way I think of truth and reality is very different from this, because I believe that there is the possibility for individual realities. Personal views and perspectives shape the world around us to a certain extent, and what we touch, smell, taste, feel, and hear, are all real to me. I don't think that the self can exist without a body, at least not in the way that we perceive 'self''. If there is no input, there is nothing to be thought, and without a mind to think, there senses of the body have no recording. One cannot exist without the other.
I trust not only my senses and reason, but also my closest family. I don't think that I trust them because I believe them to be entirely honest 100% of the time, but because I trust that they love me, and don't intend to harm me. I trust their intentions. To a degree, I also trust the people that have proven over time that they are honest; past actions speak loudly to me. The sun has risen millions of times in the past, I begin to think that it will probably rise again tomorrow.
Occasionally, there is the kind of trust that requires a leap of faith. In a way, I view this as a kind of naivety. But I still do it. This is the kind of trust that may in some cases be the strongest, because it does not come from reason, it comes from faith. It's not logical in anyway, so it really can't be argued against.
