Synthesizing happiness (without a prescription)

Of all the primary emotions, happiness is the one we’re all aching for more of. And how do we get more? We go out and grab it, right? If we’re lucky enough to have a sufficient degree of freedom, we make our choices, act carefully, get what we want and happiness follows.

The perils of reason

Reason is one of the most powerful tools we have in understanding the world around us. Most of us consider ourselves to be reasonable people, yet reason is a complicated business. Biases, fallacies, and unexamined suppressed premises can lead even careful thinkers astray and make reason a perilous road on the way to truth. This famous scene from Monty Python and the Holy Grail underlines just how tricky the actual application of reason can be.… Read the rest
