To say, that a plane is a better tool than a chisel is true only in so far as one states what the particular purpose is that it is used. Only an idiot would attempt to trim out the pocket for a door latch with a plane or to put a smooth surface on a table with a chisel. A chisel may be used in the latter case as our ancestors used them for that purpose before planes were known but we do not use them for that purpose today. To say that any one method of breeding is better than another is also foolish unless we specify the conditions
