What sets a canoeing expedition apart is that it purifies you more rapidly and inescapably than any other. Travel a thousand miles by train and you are a brute; pedal five hundred on a bicycle and you remain basically a bourgeois; paddle a hundred in a canoe and you are already a child of nature.

I am peaceful but I am not a pacifist in the philosophical sense.

I think violence is counter-productive and it is bad in democratic societies.

The politicians, who once stated that war was too complex to be left to the generals, now act as though peace were too complex to be left to themselves.

There are a lot of bleeding hearts around who just dont like to see people with helmets and guns. All I can say is go and bleed It is more important to keep law and order in society than to be worried about weak-kneed people Society must take every means at its disposal to defend itself against the emergence of a parallel power which defies the elected power.
