“Do not explain your philosophy. Embody it.”*…

Truth, knowledge, justice – to understand how our loftiest abstractions earn their keep, trace them to their practical origins…

Unlike ideas of air, food and water that allow us to think about the everyday resources we need to survive, the venerable notions of knowledge, truth or justice don’t obviously cater to practical needs. On the contrary, these exalted ideals draw our gaze away from practical pursuits. They are imbued with grandeur precisely because of their superb indifference to mundane human concerns. Having knowledge is practically useful, but why would we also need the concept of knowledge? The dog who knows where his food is seems fine without the concept of knowledge, so long as he’s not called upon to give a commencement address. And yet the concepts of knowledge, truth or justice appear to have been important enough to emerge across different cultures and endure over the ages. Why, then, did we ever come to think in these terms?

Friedrich Nietzsche grumbled that, when it came to identifying the origins of lofty ideas, philosophers had a tendency to be led astray by their own respect for them. In dealing with what they felt were the ‘highest concepts’, the ‘last wisps of smoke from the evaporating end of reality’, they had reverently placed them ‘at the beginning as the beginning’, convinced that the higher could never have grown out of the lower: Plato’s eternal Forms, the mind of God, Immanuel Kant’s noumenal world – they had all served as cradles to higher concepts, offering them a suitably distinguished pedigree.

But to insist that higher concepts were bound to have higher origins, Nietzsche thought, was to let one’s respect for those ideas get in the way of a truthful understanding of them. If, after the ‘Death of God’ and the advent of Darwinism, we were successfully to ‘translate humanity back into nature’, as Nietzsche’s felicitous rallying cry had it, we needed to trace seemingly transcendent ideas such as knowledge, truth or justice to their roots in human concerns. Their origins weren’t empyrean (to be sought in the highest spheres) but distinctly sublunary (found in lowly practical needs). Nietzsche encouraged us to ask: what necessities might have been the mothers of those inventions? And what, if anything, do they still do for us?…

* Epictetus


As we root out first principles, we might spare a thought for Sir Alfred Jules “Freddie” Ayer (usually cited as A.J. Ayer); he died on this date in 1989. A philosopher associated with the the British humanist movement, he is best remembered as the champion of of logical positivism, particularly in his books Language, Truth, and Logic (1936) and The Problem of Knowledge (1956). While he had a number of material disagreements with Nietzsche, Ayer shared his rejection of objective ethical values.


“If economists could manage to get themselves thought of as humble, competent people on a level with dentists, that would be splendid”*…


Economists have a name for this

There are plenty of economics terms regular people would find not only very interesting, but useful for thinking about policy. Sadly, the most commonly used econ words tend to be the ones with the vaguest meanings — “rational,” “equilibrium” and “efficient.” Instead, here are some of my suggestions:

• Endogeneity

Everyone knows that correlation doesn’t equal causation, but somehow people seem to forget. Endogeneity is a word that can help you remember. Something is endogenous when you don’t know whether it’s a cause or an effect (or both). For example, lots of people note that people who go to college tend to make more money. But how much of this is because college boosts earning power, and how much is because smarter, harder-working, better-connected people tend to go to college in the first place? It’s endogenous. The media is full of stories about how which kind of people stay married, or what diet is associated with better health. Whenever you see these stories, you should ask “What about endogeneity?”…

* John Maynard Keynes


As we get dismal, we might send fancy birthday greetings to Sir Frederick Henry Royce; he was born on this date in 1863.  An engineer and car designer, he founded (with Charles Rolls and Claude Johnson) the Rolls-Royce company, which introduced the first successful luxury cars in the emerging automotive industry.
