Bruce,
I have not read the essay, so I would not attempt to comment on it. However, I have heard this aphorism many times and will comment on it.
I have found that those who often cite this, do so in opposition to various government programs, but do not, at the same time, propose alternate programs for teaching people to fish. The same people who cite this often oppose government-funded programs for training, public education and the like. Perhaps you are different. I would be interested to hear a list of fishing-training programs that you support, not just what you oppose.
Also, I fail to get the connection between deism and this topic. Perhaps you can elaborate on that as well.
