A Life Guided by Reason

In #2281, I explain how Veritula helps you make rational decisions – in other words, how to live rationally, ie, a life guided by reason. (I use the words ‘reason’ and ‘rationality’ synonymously. The same goes for ‘unreason’ and ‘irrationality’.)

A life guided by reason defies the dominant, Kantian philosophy of our age. Ayn Rand summarized that philosophy as, “Be rational, except when you don’t feel like it.”1 In other words, it says to mix reason and unreason; to stray from rationality arbitrarily; to be rational only sometimes. It claims that there is a necessary clash between reason and emotion. It is an attack on reason, an attempt to do the impossible – and it leads to dissatisfaction with yourself and conflict with others.

If you are rational only sometimes, if you stray from rationality arbitrarily, then you are irrational. There is no third option. This conclusion can be proven easily: if you tried to stray from rationality non-arbitrarily, ie, if you tried to come up with a considered argument for straying from rationality, you could only do so by following the steps in #2281. And those steps are the application of rationality again.

So it’s impossible to stray from rationality rationally. There is no gray area between reason and unreason. Rationality has an all-or-nothing character. This does not mean that reason has to snuff out all emotion. On the contrary: there is no necessary clash between rationality on the one hand and emotion on the other. Rationality means finding unanimous consent between emotion, explicit thought, inexplicit thought, and any other kind of idea.

If you follow the steps in #2281 consistently, then you are always rational. A life worth living is one guided exclusively by reason. Consistent application of rationality may be difficult at first, but with practice, it will get easier. Master it, and you will have a fighting chance of becoming what David Deutsch calls a beginning of infinity.
