While other species operate by following their instincts, man alone can go above himself and look at himself within his circumstances and within time (including before and after his existence). For example, we can ponder the ways that nature’s flying machines, swimming machines, and billions of other machines, from the microscopic to the cosmic, interact with one another to make up a working whole that evolves through time. This is because the evolution of the brain gave man a much more developed neocortex, which gives us the power to think abstractly and logically.
