Loopy science more completely encompasses the core meaning of science. This non-constricting view of science seems to more easily allow for changes and new findings, which is a large part of science. As compared to linear science, loopy science more freely allows the possibilities of things to become reality. The common observation is nothing is ever the same and everything is changing little by little. Although predictions may not be initially correct at a later point in time, they could very well be shown to be true.
        
        When comparing the observations on brain and behavior of  by Descartes and Dickenson, I tend to agree with both their definitions. One does not appear to be better than the other because similar to life in general, things are not just black and white.   Physically, organisms are matter that make up the body (brain, neurons, chemical interactions), but it seems to me that these material functions are but a foundation for a “spirit” that takes the material to a whole new level.
