Theodore Roosevelt cautions J. D. Haseman that Haseman’s personal experience with piranhas is not enough to ignore the facts regarding piranhas attacking men and animals. If this is Haseman’s state of mind, he is not fit to “write a scientific book worth reading.” Scientists with more experience have stated that piranhas attack people. Roosevelt has personally viewed attacks while in South America. Haseman has a reputation for having a bad temper and ignoring facts. If he ignores the facts about piranhas, his scientific work cannot be taken seriously.
