1. One should not only be equal to any climb that one undertakes, but be more than equal to it.
2. The standard of difficulty which a climber can conquer with safety when descending, and for which he can consider himself competent, with an easy conscience, should represent the limit of what he should attempt on his ascent.
3. Hence the use of artificial aids only becomes justifiable in case of sudden threatening danger.
4. The piton is an emergency aid and not the basis of a system of mountaineering.
5. The rope may be used to facilitate matters, but never as a sole means to make a climb possible. (meaning tension traverses were OK, but not pendulums).
6. The principle of safety is one of the highest principles. Not the spasmodic correction of ones own want of safety, obtained by the use of artificial aids, but that true primary safety which should result, with every climber, from a just estimate of what he is able, and what he desires, to do.
