Beginning with the so-called Enlightenment, Western culture has imagined that "reason" is our most divine faculty and awarded high status to the mind, its imagined source. The gut is degraded because it's instinctual. The heart can't be trusted because it's fickle. No wonder many of us spend so much time in our heads. We often act as if we can reason our way to some purity, some objective clarity, but it's not possible to be human and be totally devoid of either instinct or emotion. Remember Spock? There's a reason why that notion is science fiction.
The gut and the heart have their own logic and their own perspective and we need them all to understand what is important. I think this little story speaks to the different value systems between the metaphorical head, heart, and gut in terms we can relate to today. How many fish do we need?
A rich industrialist once came upon a fisherman lying lazily beside his boat, smoking a pipe. He was horrified. "Why aren't you out fishing?" he asked the fisherman. The fisherman smiled and squinted and looked up at the industrialist. "Because I've caught enough fish for the day," he said. "But why don't you catch more?" asked the industrialist."Well what would I do with them?" the fisherman replied.
"Why you could earn more money," said the industrialist, "and buy a motor for your boat and go into deeper waters and catch more fish. Then you could make the money to buy large, nylon nets so that you could catch even more fish and make even more money. Soon you would have enough money to own two boats, maybe even a fleet of boats. Then you would be a rich man like me."
"Then what?" asked the fisherman. "Well, then you could enjoy life," replied the rich industrialist. The fisherman leaned back against his boat. "What do you think that I'm doing right now?" he said.
