"I'm only a high school student, but having recently studied the nervous system I would have to say that there is free will, if free will is defined as the ability for the brain to analyze senses and make create different options, in some cases each with a probability of living, for example if u are on the edge of a cliff, and you look down, ur eyes perceive the depth and height at which you are and this information is transmitted to ur CNS(i'm pretty sure that this isn't an automated response) and you have the choice of going closer, which increases ur probability of falling(which is going to equal death in this hypothetical situation) and backing off which will increase ur chances of survival. So now u make the choice of stepping back, if u did the opposite you are taking a risk factor. Which surprisingly is also a tendency that humans have, since evolutionary speaking living things must take risks to survive sometimes(this tendency is what drives gambling addictions and the rush u get when u win). Now the only reason why you might step forward is because of an advantage you would gain from doing this, such as respect from the community(i.e. your friends being impressed with you). If there is no advantage, then you brain will tell you to back off, and if you do the opposite that usually means ur crazy. I would consider this free will, because u do have the choice. Free will really comes into play in situations where there isn't an advantage, such as taking a left or right at an intersection(and you u don't know where either leads), where u just have to guess, and that is what free-will really is, the ability to take risks and adapt" this was another one of my posts pulled from 'How do we define life'. This is just my opinion on free-will, or our perception of free-will. I thought it would be appropriate to start a discussion on this. I do have a purpose besides just debate, my teacher has given our AP bio class a project that can be on anything involving the nervous system, I was thinking of doing a topic on this, so if you could please post some sources to help me get some solid sources when I get around to doing the project. Although I'm a little worried this kind of topic would be too advanced...all I really know is the basic sensory/analysis stuff(i.e. action potentials, and I know how most sensory receptors create action potentials, and I know the basic functions of the different parts of the brain, and basic brain anatomy) So if anyone has any hints as to where I should look for more info, and it would be cool if I could discuss my ideas with you guys/gals too.
