While politicians, entrepreneurs, and even school children could tell you that sustainability is an important and nearly universal value, many of them, and many of us, may struggle to define the term, let alone trace its history. What is sustainability? Is it always about the environment? What science do we need to fully grasp what it requires? What does sustainability mean for business? How can governments plan for a sustainable future? 

To give and receive well may be the most human thing you can do-but it is also the closest you can come to divinity. So argues the great Roman Stoic thinker Seneca in his longest and most searching moral treatise, "On Benefits" (De Beneficiis). James Romm's splendid new translation of essential selections from this work conveys the heart of Seneca's argument that generosity and gratitude are among the most important of all virtues.

The ancient biographer and essayist Plutarch thought deeply about the leadership qualities of the eminent Greeks and Romans he profiled in his famous - and massive - Lives, including politicians and generals such as Pericles, Alexander the Great, Julius Caesar, and Mark Antony. Luckily for us, Plutarch distilled what he learned about wise leadership in a handful of essays, which are filled with essential lessons for experienced and aspiring leaders in any field today. 

Artificial intelligence powers Google's search engine, enables Facebook to target advertising, and allows Alexa and Siri to do their jobs. AI is also behind self-driving cars, predictive policing, and autonomous weapons that can kill without human intervention. These and other AI applications raise complex ethical issues that are the subject of ongoing debate. This volume in the MIT Press Essential Knowledge series offers an accessible synthesis of these issues.

Everywhere we hear talk of decline, of a world that was better once, maybe fifty years ago, maybe centuries ago, but certainly before modernity drew us along its dubious path. While some lament the slide of Western culture into relativism and nihilism and others celebrate the trend as a liberating sort of progress, Charles Taylor calls on us to face the moral and political crises of our time, and to make the most of modernity’s challenges.

Noted transcendentalist Henry David Thoreau spent two years, two months, and two days chronicling his near-isolation in the small cabin he built in the woods near Walden Pond on land owned by his mentor, the father of Transcendentalism, Ralph Waldo Emerson. Immersing himself in nature and solitude, Thoreau sought to develop a greater understanding of society amidst a life of self-reliance and simplicity. Originally published in 1854, Walden remains one of the most celebrated works in American literature.

In What We Owe The Future, philosopher William MacAskill argues for longtermism, that idea that positively influencing the distant future is a key moral priority of our time. It’s not enough to reverse climate change or avert the next pandemic. We must ensure that civilization would rebound if it collapsed, counter the end of moral progress, and prepare for a planet where the smartest beings are digital, not human. If we set humanity’s course right, our grandchildren’s grandchildren will thrive, knowing we did everything to give them a world of justice, hope, and beauty.

Is it sexist to say that “men are trash”? Can white people be victims of racism? Do we bear any individual responsibility for climate change? We’ve all wrestled with questions like these, whether we’re shouting at a relative across the dinner table, quarreling with old classmates on...

The Prince is a classic work of political philosophy by famous political theorist Niccolò Machiavelli. A phrase often associated with this work is “the ends justify the means.” In other words, Machiavelli believed that acts of cruelty or lawbreaking were justifiable if the purpose of such acts was to advance one’s own power and chances of survival. The adjective “Machiavellian” refers to behaving in a way that aligns with Machiavelli’s philosophy. To this day, Machiavelli’s philosophy is controversial.
