Science, as I pointed out in the previous chapter, is flexible and nondogmatic. It sticks to facts and to reality (which always can change) and to logical thinking (which does not contradict itself and hold two opposite views at the same time). But it also avoids rigid all-or-none and either/or thinking and sees that reality is often two sided and includes contradictory events and characteristics. Thus, in my relations with you, I am not a totally good person or a bad person but a person who sometimes treats you well and sometimes treats you badly. Instead of viewing world events in a rigid, absolute way, science assumes that such events, and especially human affairs, usually follow the laws of probability.
