Notes and topics
"The principle of abstraction defining property in terms of class membership appeared first in the Principles of Mathematics—e.g. Chapter XIX, paragraph 157 (page 166) and Chapter XXVI, paragraph 210 (page 219). I am not quite certain that this is the first time I mentioned the principle, but it is the first mention that I have been able to find."
