He does not know that an expert laughs at the difficulties of a beginner, which never trouble a man when he has become expert.
As well might a man the first time he is put on a horse imagine that, because he has to fly up and down off the saddle at each movement of a cantering horse, that the expert also has to take care not to fall off.
The expert can sit on a cantering horse without the least lifting from the saddle, whereas the beginner flops up and down.
In the same way the expert shot has passed the stage which the inexpert inventor tries to invent against.
A horseman would not buy a saddle with straps to tie down the rider, invented by a man who did not ride.
The non-rider thinks such things absolutely necessary to keep from falling off, the expert horseman not only knows such things are unnecessary, but would be a danger in case the horse fell, as the rider could not fall clear.
In the same way inventors of firearms, if they are not shooting men, invent dangerous things for overcoming dangers which do not exist except in their own imaginations.
This would not matter so much if they would listen to experts but they refuse to learn, and actually try to instruct experts.
I had a man come in recently to show me a terribly dangerous pistol he had invented.
He was pointing it about in all sorts of dangerous directions and finally put the muzzle against his own body whilst he tried to cock it.
