Consider two of my properties: my mass and my weight. There seems to be an interesting distinction between the reasons for my having these two properties. I have my mass solely in virtue of how I am, whereas I have my weight in virtue of both how I am and how my surroundings are. I have my weight as a result of the gravitational pull exerted by the Earth on a thing having my mass, whereas I have my mass independently of other things around me. If you change my surroundings, if you put me on the moon say, my weight will change, but my mass will stay the same
