What Is Intelligence?

The West’s Dangerous Obsession With Analytical Intelligence

Everyone wants to be intelligent. But no one is quite intelligent enough to know what intelligence is.

There is no agreed definition or model of intelligence. By the Collins English Dictionary, intelligence is ‘the ability to think, reason, and understand instead of doing things automatically or by instinct’. By the Macmillan Dictionary, it is ‘the ability to understand and think about things, and to gain and use knowledge’.

In seeking to define intelligence, a good place to start might be with dementia. In Alzheimer’s disease, the most common form of dementia, multiple higher cortical functions are disturbed, including memory, thinking, orientation, comprehension, calculation, learning capacity, language, and judgement. In my time, I have worked with over a thousand people with dementia, and I think it significant that they, along with people with severe learning disabilities, cope very poorly with changes to their environment, such as moving into a care home or even into an adjacent room.

Taken together, this suggests that, at its broadest, intelligence refers to the functioning of a number of related faculties and abilities that enable us to adapt and respond to environmental pressures. Because this is not beyond animals and even plants, they too may be said to be possessed of ‘intelligence’.

We Westerners tend to think of intelligence in terms of analytical skills. But in a close-knit hunter-gatherer society, intelligence might be defined more in terms of foraging skills, hunting skills, or social skills and responsibilities. Even within a single society, the skills that are most valued change over time.

In the West, the emphasis has gradually shifted from language skills to more purely analytical skills, and it is only in 1960, well within living memory, that the Universities of Oxford and Cambridge dropped Latin as an entry requirement.

In 1990, Peter Salovey and John Mayer published the seminal paper on emotional intelligence, and EI quickly became all the rage. In that same year, Tim Berners-Lee wrote the first web browser. Today, we cannot go very far without having some considerable IT skills (certainly by the standards of 1990, or even 2010), and computer scientists are among the most highly paid professionals.

All this to say that what constitutes intelligence can vary quite considerably according to our values and priorities.

The West Before the West

The Western privileging of analytical skills is rooted in Ancient Greece—but the story is more complicated than it first appears.

Before Socrates, there was the Oracle at Delphi. For centuries, prominent Greeks travelled to Delphi to consult the Pythia, the priestess of Apollo, whose cryptic pronouncements were thought to issue from the god of light. One of these pronouncements concerned Socrates himself.

According to Plato and Xenophon, Socrates’ friend Chaerephon asked the oracle whether anyone was wiser than Socrates. The Pythia replied in the negative. When Socrates found out about this, he did not know what to make of it. So he went about questioning one man after another, first the politicians, then the poets, and then the craftsmen, and found that those with the greatest reputation for wisdom were, in fact, the most foolish of them all. By this exercise, he came to understand the oracle’s meaning: that the wisdom of men is little or nothing, and those who know this are as wise as any man can be. Inspired by this revelation, he entered the service of Apollo, seeking out anyone who laid claim to wisdom and putting his wisdom to the test.

Thus, one of the founding stories of Western rationalism begins not with some argument, but with a rather irrational oracle.

Socrates held that ‘the unexamined life is not worth living’. He typically taught by the dialectic or Socratic method, that is, by questioning one or more people about a particular concept such as courage or justice to expose a contradiction in their initial assumptions and provoke a reappraisal of the concept.

But even Socrates, the great champion of rational enquiry, made room for another kind of knowing. At various times, he claimed to have a daimonion or ‘divine sign’, an inner voice or intuition that prevented him from making grave mistakes such as going into politics or fleeing Athens after having been sentenced to death. When, in Plato’s Crito, his friends urge him to flee Athens, he refuses on the authority of his daimonion: ‘This is the voice which I seem to hear murmuring in my ears, like the sound of the flute in the ears of the mystic; this voice, I say, is humming in my ears, and prevents me from hearing any other.’

So here we have it: the father of Western rationalism, in hock to some mysterious voice.

The Rule of Reason

Plato and Aristotle built upon the legacy of Socrates, while underplaying his more mystical side.

For Plato, reason could carry us far beyond the confines of common sense and everyday experience into a ‘hyper-heaven’ (Greek, hyperouranos) of ideal forms. He famously fantasised about putting a geniocracy of philosopher kings in charge of his utopic Republic.

Aristotle—who for centuries came to be known simply as ‘our Master’—argued that our distinctive function as human beings is our unique capacity to reason, and therefore that our supreme good and happiness consists in leading a life of rational contemplation. To paraphrase Aristotle in Book X of the Nicomachean Ethics, ‘Man more than anything is reason, and the life of reason is the most self-sufficient, the most pleasant, the happiest, the best, and the most divine of all.’

And with that, where else could the West go?

Aristotle, in the Metaphysics, also conceived of God as ‘thought thinking upon itself’ (noesis noeseos). In later centuries, reason became a divine property, found in man because made in God’s image. If you struggled with your SATs, you now know who to blame.

When Intelligence Becomes Human Worth

As I argue in Hypersanity: Thinking Beyond Thinking, the West’s obsession with analytical intelligence has had, and continues to have, dire political, social, and, above all, moral consequences.

Immanuel Kant—probably the most influential philosopher since Aristotle—most memorably made the connection between reasoning and moral standing, arguing (in simple terms) that, by virtue of their ability to reason, human beings ought to be treated, not as means to an end, but only ever as ends-in-themselves. From here, it becomes all too easy to conclude that, the better you are at reasoning, the worthier you are of personhood and its rights and privileges.

For centuries, women were deemed to be ‘emotional’, that is, irrational, or less rational, which justified treating them as chattel or, at best, second-class citizens. The same could also be said of non-white people, over whom it was not just the right but the duty of the white man to rule.

Rudyard Kipling’s poem The White Man’s Burden (1899) begins with the lines: Take up the White Man’s burden–/ Send forth the best ye breed–/ Go bind your sons to exile/ To serve your captives’ need;/ To wait in heavy harness/ On fluttered folk and wild–/ Your new-caught, sullen peoples,/ Half-devil and half-child.

Although this sounds appalling today, at the time most of Kipling’s countrymen would have approved of the sentiment. In his lifetime, Kipling was offered (and turned down) a knighthood, the position of Poet Laureate, and the Order of Merit. He was not writing from the fringes.

People deemed to be less rational—women, non-white people, the lower classes, the infirm, the ‘deviant’—were not just disenfranchised but dominated, colonised, enslaved, murdered, and sterilised, in all impunity. As late as 2015, Virginia agreed to compensate surviving victims of its state-sponsored sterilisation programme for, among others, the ‘feeble-minded’.

Today, of all people, it is the white man (that is, the white male) who most fears artificial intelligence, imagining that it will usurp his status and privilege.

But even on its own terms, analytical intelligence is not quite what we make of it.

According to science, IQ is the best predictor of job performance. But that is not altogether surprising given that ‘performance’ and IQ have been defined in similar and overlapping terms, and that both depend, at least to some extent, on third factors such as compliance, motivation, and educational attainment.

Genius, in contrast, is more a matter of drive, vision, creativity, and luck or opportunity, and it is notable that the threshold IQ for genius—probably around 125—is not all that high.

William Shockley and Luis Walter Alvarez, who both went on to win the Nobel Prize for physics, were excluded from the Terman Study of the Gifted on account of… their unremarkable IQ scores.

In later life, Shockley developed controversial views on race and eugenics, using his ‘formidable intellect’ to make claims about the intelligence and worth of others.

And so it was that a Nobel Prize winner who had failed to qualify as ‘gifted’ came to advocate eugenic measures on the basis of supposed differences in intelligence.

Of course, analytical intelligence is of value. But it is not intuition, it is not imagination, and it is not wisdom.
