An Intricate Machine

I think and therefore I am. I am aware of myself and therefore I am. I feel deeply and therefore I am. But what am I? I am an Intricate Machine. I am not made with wires. I am not made with metal or plastic. I was not designed in a lab somewhere but I am still a machine. I have inputs that tell me about the world around me. I have eyes to see what is around me and where I am going. I have ears to listen to vibrations that travel through the air. I have hands with the ability to feel and distinguish if something is smooth or rough. I can put something in my mouth and determine whether is it sweet or bitter. These inputs travel to my brain. My brain is the central processing system of my body. My brain takes these inputs and performs calculations on them. Based on parameters inside my brain, my brain decides what actions to take based on the results of the calculations. I have outputs to affect the world around me. I have feet that can move me from one place to another. I have hands that allow me grab things and manipulate them. I have a voice and allows me to send sound waves through the air. This is the process of any machine, the recieve inputs, process those inputs, and then output something. I can only produce outputs that are the results of the calculations my brain makes. There are parameters currently set in my brain. Can those parameters change? Absolutely. The things that my input sensors deliver to my central processing center can change the parameters. There are also triggers that are internally built in that can change them. I think I have a will. I think my will is free but the truth is that I can only do things based on the inputs and parameters that are currently set in my brain.
