Law 9 of The 48 Laws of Power by Robert Greene is "Win through your actions, never through argument". This law suggests that winning an argument may provide a temporary advantage, but winning through actions will result in lasting power. 

Here are some reasons why actions are more powerful than arguments:Actions demonstrate competence: Actions show that you are capable and create value. 

Arguments lead to negative emotions: Arguments can stir up resentment and ill will that can last longer than any temporary change in opinion. 

Demonstrate, don't explicate: It's more effective to get others to agree with you through your actions, rather than explaining your position.
