It is argued that Psychology has gone through many competing paradigms such as the Instrospectionists, Humanist, Behaviorists, Cognitivists and more.

The only reason that no psychologist has been burned at the stake is that there are laws.

• Science has developed as it has today because of its success. We have a philosophical outlet and practical methodologies that let us explore the world.
  
  
• We have procedures that can discover and test the lawful nature of many things - especially in Psychology.
  
  
• We are no longer tyrannized by appeals to authority.
  
  
• We form hypotheses and we TEST them. Our decisions are based on the results.
  
  
• In fact, rather than fearing change, we await the next scientific revolution with anticipation as who knows what progress it may bring us.
