For as long as I can remember I have been told that there is an objective and neutral "truth" out there. Scientists are supposed to discover this truth and share it with the world. Employers, legislators, bureaucrats, teachers, and parents are also supposed to have this objectivity/neutrality toward their subordinates in deciding who gets the job, who benefits from a government program, what grades students receive for their efforts, etc.
Unfortunately, we live in a subjective world. All of our social choices are influenced by thousands of factors making any decision neutrality impossible. Our thoughts and actions cannot be neutral! What this means on a practical level is that every one of our decisions will have either a positive or negative impact on the world.
So, if now you realize that everything you do, every thought you have in passing will change the world in some way, what kind of world are you building?
