Geoffrey West’s *Scale* unlocks the hidden mathematical laws governing everything from tiny bacteria to sprawling megacities, and from startup firms to global economies. Blending physics, biology, sociology, and economics, this landmark work reveals how nonlinear scaling—sublinear for biological systems and urban infrastructure, superlinear for urban innovation and corporate risks—shapes growth, resilience, and mortality. Through vivid, relatable examples, from the fatal miscalculation of LSD doses for elephants to the flawed linear logic of children’s Tylenol dosage, West shows why ignoring scale laws leads to costly, even deadly, mistakes. He explores how cities thrive on superlinear gains in creativity and wealth (alongside rising crime and disease), while companies follow biological-like sublinear growth that dooms most to collapse within a decade. Ultimately, *Scale* offers a unified framework to confront humanity’s biggest challenge: building sustainable systems that balance exponential growth with Earth’s finite limits, using innovation to avoid the "finite-time singularity" that threatens unchecked expansion.

Steven Pinker

In Enlightenment Now, Steven Pinker delivers a sharp, data-backed defense of the Enlightenment’s core values—reason, science, humanism, and progress—against rising pessimism and anti-Enlightenment backlash. Drawing on cross-disciplinary research, Pinker dismantles the myth of global decline, highlighting tangible improvements: eradicated diseases, plummeting extreme poverty, reduced war deaths, and expanded civil rights. He addresses critics from romanticists to religious conservatives, explaining how their rejection of rationality ignores decades of human progress. Pinker also confronts modern threats like nuclear war, populism, and climate change, arguing that doubling down on Enlightenment principles is the only way to navigate future challenges. This isn’t just a celebration of the past; it’s a blueprint for sustaining humanity’s upward trajectory by prioritizing evidence, empathy, and collective rationality.
