Reading a fun book called Jitterbug Perfume by Tom Robbins. The subject being among other things longevity and immortality, which if you know me based on my writings here, is right up my alley.
Anyway, I found this fun passage to quote, which seems in my mind to be a pretty good defense of secrecy, of why some things shouldn't be open source and freely available to any fool who lacks the wisdom and integrity to properly understand and apply what they learn in the way that it was intended. Doing so opens the doors of such wisdom being misused and abused in such a way that it no longer resembles wisdom.
From Jitterbug Perfume:
"Those who possess wisdom cannot just ladle it out to every wantwit and jackanapes who comes along and asks for it. A person must be prepared to receive wisdom, or else it will do him more harm than good. Moreover, a lout thrashing about in the clear waters of wisdom will dirty those waters for everyone else. So, a man seeking knowledge must be first tested to determine if he is worthy. From what I have gathered, rudeness on the part of the master is the first phase of the test.
"You mean, if you allow the master to be uncivil, to treat you any old way he likes, and to insult your dignity, than he may deem you fit to hear his views of things?
"Quite the contrary. You must defend your integrity, assuming you have integrity to defend. But you must defend it nobly, not by imitating his own low behavior. If you are gentle where he is rough, if your are polite where is uncouth, then he will recognize you as potentially worthy. If he does not, then he is not a master, after all, and you may feel free to kick his ass."
