Enlightenment Now

The Case for Progress

Steven Pinker is a cognitive psychologist at Harvard whose previous book, The Better Angels of Our Nature, made the data-backed case that violence has declined dramatically over human history. Enlightenment Now extends that argument to 75 dimensions of human well-being — health, wealth, food, peace, knowledge, freedom, happiness, safety, democracy — and finds improvement across virtually all of them.

This is not a comforting book so much as a challenging one. It asks: why does the dominant cultural narrative — from both progressive and conservative quarters — insist that things are getting worse, when the data so consistently shows the opposite? And it argues that this pessimism is not merely wrong but genuinely dangerous, because it erodes support for the institutions and values that have produced the progress.

The Data on Progress

The book’s first section is an extended exercise in quantitative literacy. Pinker graphs centuries of data on life expectancy, child mortality, extreme poverty, literacy, war deaths, accidental deaths, democratic governance, and dozens of other measures. The picture across almost all of them is the same: a long plateau of stagnation followed by dramatic improvement over the last two to three centuries, with acceleration in the twentieth century.

The directness of this evidence is striking. We are, on average, richer, healthier, safer, freer, and more educated than at any prior point in human history. The question of why this doesn’t feel true is as interesting as the data itself.

Enlightenment Values as Cause

Pinker’s argument is not merely that things have gotten better but that they have gotten better because of specific values: reason, science, humanism, and a commitment to progress. These values, crystallised in the European Enlightenment and spread through scientific and political institutions, are not culturally parochial — they represent the set of principles that actually work for improving human well-being.

Where the Critics Have a Point

Pinker’s optimism is sometimes more triumphalist than the evidence warrants. Environmental limits on growth, the risks of nuclear and biological weapons, and the challenges of inequality are not adequately addressed by data showing past improvement. Progress is real; the continuation of progress is not guaranteed.

The Psychology of Pessimism

One of the book’s most genuinely useful arguments concerns not the data itself but why we are so resistant to it — why, in an age of unprecedented improvement across nearly every measure of human welfare, the dominant cultural mood is one of decline and dread. Pinker draws on cognitive psychology to explain the gap, identifying the mental habits that bias us toward pessimism: the availability heuristic, which makes vivid catastrophes feel more representative than they are; the negativity bias, which weights bad news more heavily than good; and a news media whose business model rewards alarm, since the steady, incremental nature of progress is undramatic and unreportable while every disaster is breaking news. Bad things happen quickly and make headlines; good things, like the gradual halving of global extreme poverty, accumulate invisibly over decades. This analysis is valuable independent of one’s view of Pinker’s broader thesis, because it offers a framework for thinking more clearly about risk and progress and for resisting the reflexive doom that distorts public discourse and, Pinker argues, can become self-fulfilling.

The Case for the Enlightenment

The book’s deeper ambition is not merely to document progress but to defend the philosophical project Pinker credits with causing it: the Enlightenment values of reason, science, humanism, and progress itself. His argument is that the dramatic improvements in human welfare over the past two centuries are not accidents but the fruits of a specific set of ideas — the commitment to applying reason and empirical inquiry to human problems, the humanistic conviction that the reduction of suffering and the flourishing of individuals is the proper aim of institutions, and the belief that knowledge can be marshaled to make life better. Pinker mounts this defense against what he sees as the enemies of Enlightenment on both the political left and right: religious fundamentalism, romantic nationalism, declinism, and strands of academic thought that he argues have abandoned faith in reason and progress. This polemical dimension gives the book its energy and its edge, and it is also where it is most contested, since not all readers share Pinker’s confidence that “the Enlightenment” is a single coherent project or that its values are as universally applicable as he claims.

Triumphalism and Its Critics

In fairness, the criticisms of Enlightenment Now are substantial and deserve acknowledgment, because Pinker’s optimism sometimes outruns what his evidence can support. Showing that violence, poverty, and disease have declined over the past two centuries does not guarantee that progress will continue, and critics rightly note that the book gives inadequate weight to the gravest threats to that continuation: catastrophic climate change, the ecological limits of growth, the existential risks of nuclear and biological weapons and advanced technology, and the corrosive effects of extreme inequality. Past improvement is not a promise about the future, and a few of these challenges are arguably of a different kind than those the Enlightenment has already overcome. Pinker can also be selective and combative, marshaling data to score points against intellectual opponents and underplaying complications that don’t fit his narrative. These are real limitations. But they qualify rather than refute the core contribution: even granting every caveat, the documented fact of dramatic human progress is something most people simply do not know, and confronting it honestly is genuinely clarifying.

Final Verdict

Enlightenment Now is the most comprehensive and data-rich defence of optimism and Enlightenment values ever written. Its limitations are real but do not undermine its core contribution.

Our rating: 4.4/5 — An important and frequently necessary counterweight to default pessimism. Read the data carefully and apply the appropriate nuance.
