I'm a first year medical student, and before one of our anatomy practicals, the second year students were holding a review. One second year student stood at a cadaver and pointed to different structures, asking students to name them round robin style. As she was asking questions, she was grasping the cadaver's penis and pointing it at people to call on them.
In my opinion, this action was in good taste. In fact, it was hilarious.
Only living conscious beings should be treated with respect. The very concept of respect is absurd when it is obscured from the emotions of a conscious being. Indeed, disrespect is intuitively associated with offense and other negative emotional reactions.
As for the issue of a soul, I challenge any of you to provide good evidence against philosophical monism.
As for my cadaver: Harvest it for organs, chop it up for fun/education, laugh at its irregularities, cook and eat it, ass-rape it, skull **** it, film it in bukake porn...do whatever you'd like. Just get some good use out of it.
