So it’s not the 20th anymore but it’s close enough. Here’s one of my all-time favorite quotes.
No concept man forms is valid unless he integrates it without contradiction into the total sum of his knowledge.
this quote has always struck a cord with me as it perfectly describes how I approach philosophy and thinking. Whatever it is you think it should be consistent with everything else you think. You should not believe contradictory things and you should not apply logic differently to different areas of your life. It is similar to Kant’s Categorical Imperative which is a mechanism used to determine the validity of our actions. In short, when determining whether or not to do something you ask yourself if everyone did this would it work or make sense to do. If the answer is yes then its fine, if not then it’s not fine and you shouldn’t do it. Now, that’s just a quick idea of what it’s like but it gets the point across. Be consistent in what you think and what you do and that should be consistent with how the world and those individuals who make up what we call society.
Just some food for thought. I hope this gives you another perspective on any introspective considerations you make.
