“Dogmas and formulas, those mechanical instruments for rational use (or rather misuse) of his natural endowments, are the ball and chain of his permanent immaturity.” Here Kant is referring to how when people are given something to them they’re whole lives, and are comfortable with it, it leads to no innovation. Which makes me think of the Apple Iphone. I dont hate apple, nor am I an Android fanboy, but all it takes is observation to see how comfortably Apple has been sitting on the phone. Although slowly loosing market share to Android.
