When I went back inside the house, I tried researching exactly what ownership meant. To my surprise, I found that Harvey Reeves Calkins (1915) researched this topic and presented his findings in a book titled, A Man and His Money. In it he claims that ancient Roman Law is the foundational philosophy on which ownership rests.
But that invisible bond between a person and what s/he owns seems somewhat selfish. Calkins claimed that "Ownership signifies the nearness, or possible nearness, of other people who can be hindered from possessing or enjoying the thing that is mine. In a word, ownership means hindrance;" meaning: keep others from taking what I own.
I hunted for more up-to-date meanings of ownership to find that Encarta Encyclopedia (2005) claims that "Ownership involves, first and foremost, possession," but since I was not grasping or wearing the t-shirt, accordingly, ownership would seem questionable.
Encarta goes on to say that with any property: "ownership in modern societies implies the right to use, prevent others from using . . . ." In my mind, this prevention means brute force. To me, there are two points clearly evident from my weed pulling experience:
1) There is a world of invisible "thingies" for want of a better term, and ownership is one of them.
2) The best way to prove the t-shirt is mine is to keep it on or to use brute force. If an intruder lifted it and refused to give it back, only if I was larger and more muscular than the thief could I clobber the robber into returning it.
Is a sweaty, smelly t-shirt, attached to me with no strings, worth a black eye?
