This is a pretty great background on Stephen Downes’ appearance in #Philosophy12 (specifically, Logic).
With my limited knowledge of Stephen Downes, I suspect these all to be true. His territory is the internet, which he prowls with the knowledge that if he sees non-desirable behavior, he will put an end to it. We can see this from the recent slew of comments this blog has received from him, in which he combats the non-desirable behavior of faulty logic. As he is not part of any organization, nor is this blog any sort of immediate or non immediate threat, he is under his own initiative to do this. Through reactions from other students, I am able to see that he inspires a certain amount of fear, but there has been nothing fatal. A time stamp from one of his comments will show that he commented in what would be the dead of night in this time zone. And finally, Downes does not use superpowers, he uses the advanced knowledge and skills in philosophy and logic that he has trained to obtain. The second premise seems to be true.
There is only one conclusion.
