I don't have any particular opinion one way or another about sea level rise, TIA. I'm not informed enough about it to have any opinion.

However, I am acquainted with dowsing, I know that it works (though I am not quite sure how it works exactly), and I think it's silly for you to take a cheap shot at someone because he believes in dowsing and wanted to teach a course on it. You can teach a course on dowsing, it does work, and it's a very interesting and useful technique for locating underground water and many other things as well.

You can detect the strength of a person's energetic field (which is all around their body at all times) by dowsing. I've done it. It's the simplest thing in the world to do it, anyone can do it, and it is consistent and accurate. You can weaken their field or strengthen it by having them do various things. For instance, if they think about something that makes them feel happy, their field strengthens and enlarges. If they think about something that frightens or depresses them, their field weakens and contracts. This indicates dramatically that the state of your thoughts affects your entire nervous system (the generator of your energetic field)...an excellent reason for learning to govern your thoughts better and not keep sliding into negative thoughts like worry, anger, hatred, revenge, resentment, bitterness, etc...because to do so weakens your entire biological system and can eventually cause serious illness to manifest.

There's absolutely no reason why someone should not teach a university course on dowsing...other than the stark ignorance and prejudice of people who know nothing about it themselves, and therefore figure it can't possibly be real.

Remember: I am making no statement here either pro or con about sea level rise. I am simply saying that you shouldn't take a cheap shot at someone over his belief in dowsing. It's kind of like the old "little green men" canard that people trot out whenever someone tries to seriously discuss a UFO incident.
