No, scientific reduction is the way in which we make complex systems and interactions easier to study, however it is not the be all and end all. It is useful but not absolute.
''Unlike Newtonian physics, modern research takes into account the complex interactions between the particles, rather than looking at them individually.
Chaotic systems, such as turbulence, weather patterns and even the behavior of crowds are difficult to explain by the process of scientific reductionism.
In addition, isolating one phenomenon and studying it often changes its behavior. For example, it is impossible to measure both the position and speed of an electron, because measuring one affects the other. Therefore, the very purest reductionist principles cannot be used to describe anything.
The common consensus seems to be that scientific reductionism is too flawed to act as a valid philosophical viewpoint. Aside from the problems involved in applying the idea to abstract ideas such as emotion and being, it is very impractical. Many areas, such as quantum physics, are too complicated to describe by studying the individual parts, and doing so does not always give the best picture.''
