In the years between her first public lecture in 1961 and her last in 1981, Ayn Rand spoke and wrote about topics as different as education, medicine, Vietnam, and the death of Marilyn Monroe. In The Voice of Reason, these pieces are gathered together in book form for the first time. Written in the last decades of Rand's life, they reflect a life lived on principle, a probing mind, and a passionate intensity. With them are five essays by Leonard Peikoff, Rand's longtime associate and literary executor.

In his groundbreaking and controversial book The DIM Hypothesis, Dr. Leonard Peikoff casts a penetrating new light on the process of human thought and thereby on Western culture and history. In this far-reaching study, Peikoff identifies the three methods people use to integrate concrete data into a whole, as when connecting diverse experiments by a scientific theory, separate laws into a constitution, or single events into a story.

In the 1960s and early '70s, the most prominent, vocal cultural movement was the New Left: a movement that condemned America and everything it stood for: individualism, material wealth, science, technology, capitalism.

This is Ayn Rand's challenge to the prevalent philosophical doctrines of our time and the "atmosphere of guilt, of panic, of despair, of boredom, and of all-pervasive evasion" that they create. One of the most controversial figures on the intellectual scene, Ayn Rand was the proponent of a moral philosophy, an ethic of rational self-interest, that stands in sharp opposition to the ethics of altruism and self-sacrifice.

This brilliantly conceived book is based on a lecture course given by Dr. Leonard Peikoff in 1976 entitled, "The Philosophy of Objectivism". The lectures were attended by Ayn Rand, who helped prepare them and who also joined Peikoff in answering questions.

Loving Life demonstrates that morality is not a matter of divine revelation nor social convention nor personal opinion but a matter of the factual requirements of human life and personal happiness. Biddle shows how a true morality is derived logically from observable facts, what in essence such a morality demands, and why it is a matter of pure self-interest.

Who needs philosophy? Ayn Rand's answer: Everyone. This collection of essays was the last work planned by Ayn Rand before her death in 1982. In it, she summarizes her view of philosophy and deals with a broad spectrum of topics. According to Ayn Rand, the choice we make is not whether to have a philosophy, but which one to have: a rational, conscious, and therefore practical one, or a contradictory, unidentified, and ultimately lethal one.

The Pleasure of Finding Things Out is a magnificent treasury of the best short works of Richard P. Feynman, from interviews and speeches to lectures and printed articles. A sweeping, wide-ranging collection, it presents an intimate and fascinating view of a life in science - a life like no other. From his ruminations on science in our culture to his Nobel Prize acceptance speech, this book will delight anyone interested in the world of ideas.

We've all heard that the American Dream is vanishing, and that the cause is rising income inequality. The rich are getting richer by rigging the system in their favor, leaving the rest of us to struggle just to keep our heads above water. To save the American Dream, we're told that we need to fight inequality through tax hikes, wealth redistribution schemes, and a far higher minimum wage.

How much can we know about the world? In this audiobook physicist Marcelo Gleiser traces our search for answers to the most fundamental questions of existence, the origin of the universe, the nature of reality, and the limits of knowledge. In so doing he reaches a provocative conclusion: Science, like religion, is fundamentally limited as a tool for understanding the world. As science and its philosophical interpretations advance, we face the unsettling recognition of how much we don't know.

For over a decade, philosopher and energy expert Alex Epstein has predicted that any negative impacts of fossil fuel use on our climate will be outweighed by the unique benefits of fossil fuels to human flourishing--including their unrivaled ability to provide low-cost, reliable energy to billions of people around the world, especially the world’s poorest people. And contrary to what we hear from media “experts” about today’s “renewable revolution” and “climate emergency,” reality has proven Epstein right.

Rand takes listeners step by step through the writing process, providing insightful observations and invaluable techniques along the way. She discusses the psychological aspects of writing and the roles played by the conscious and subconscious mind. She talks about articles and books, explaining how to select a subject and theme, how to identify your audience, and how to write the first draft.

Perhaps one of the most revolutionary works of philosophy ever presented, The Phenomenology of Spirit is Hegel's 1807 work that is in numerous ways extraordinary. A myriad of topics are discussed, and explained in such a harmoniously complex way that the method has been termed Hegelian dialectic. Ultimately, the work as a whole is a remarkable study of the mind's growth from its direct awareness to scientific philosophy, proving to be a difficult yet highly influential and enduring work.

A good book may have the power to change the way we see the world, but a great book actually becomes part of our daily consciousness, pervading our thinking to the point that we take it for granted, and we forget how provocative and challenging its ideas once were - and still are. The Structure of Scientific Revolutions is that kind of book.

After the publication of Atlas Shrugged in 1957, Ayn Rand occasionally lectured in order to bring her philosophy of Objectivism to a wider audience and apply it to current cultural and political issues. These taped lectures and the question-and-answer sessions that followed added not only an eloquent new dimension to Ayn Rand's ideas and beliefs, but a fresh and spontaneous insight into Ayn Rand herself.

In this rich, irreverent, and compelling history, Nobel Prize-winning physicist Steven Weinberg takes us across centuries, from ancient Miletus to medieval Baghdad and Oxford, from Plato's Academy and the Museum of Alexandria to the cathedral school of Chartres and the Royal Society of London. He shows that the scientists of ancient and medieval times not only did not understand what we understand about the world--they did not understand what there is to understand or how to understand it.

Utterly beautiful. Profoundly disconcerting. Quantum theory is quite simply the most successful account of the physical universe ever devised. Its concepts underpin much of the 21st-century technology that we now take for granted. But at the same time it has completely undermined our ability to make sense of the world at its most fundamental level.

Nobel Laureate Eugene Wigner once wondered about "the unreasonable effectiveness of mathematics" in the formulation of the laws of nature. Is God a Mathematician? investigates why mathematics is as powerful as it is. From ancient times to the present, scientists and philosophers have marveled at how such a seemingly abstract discipline could so perfectly explain the natural world. More than that - mathematics has often made predictions, for example, about subatomic particles or cosmic phenomena that were unknown at the time, but later were proven to be true.

In trying to understand the atom, physicists built quantum mechanics, the most successful theory in science and the basis of one-third of our economy. They found, to their embarrassment, that with their theory, physics encounters consciousness. Authors Bruce Rosenblum and Fred Kuttner explain all this in nontechnical terms with help from some fanciful stories and anecdotes about the theory's developers. They present the quantum mystery honestly, emphasizing what is and what is not speculation.

A good book may have the power to change the way we see the world, but a great book actually becomes part of our daily consciousness, pervading our thinking to the point that we take it for granted, and we forget how provocative and challenging its ideas once were - and still are.

The latest developments in physics have the potential to radically revise our understanding of the world: its makeup, its evolution, and the fundamental forces that drive its operation. Knocking on Heaven's Door is an exhilarating and accessible overview of these developments and an impassioned argument for the significance of science. There could be no better guide than Lisa Randall.

Einstein and the Quantum reveals for the first time the full significance of Albert Einstein's contributions to quantum theory. Einstein famously rejected quantum mechanics, observing that God does not play dice. But, in fact, he thought more about the nature of atoms, molecules, and the emission and absorption of light - the core of what we now know as quantum theory - than he did about relativity.

Warped Passages is an altogether exhilarating journey that tracks the arc of discovery from early 20th-century physics to the razor's edge of modern scientific theory. One of the world's leading theoretical physicists, Lisa Randall provides astonishing scientific possibilities that, until recently, were restricted to the realm of science fiction. Unraveling the twisted threads of the most current debates on relativity, quantum mechanics, and gravity, she explores some of the most fundamental questions posed by Nature.

Far too often, public discussion of science is carried out by journalists, voters, and politicians who have received their science secondhand. The Story of Western Science shows us the joy and importance of reading groundbreaking science writing for ourselves and guides us back to the masterpieces that have changed the way we think about our world, our cosmos, and ourselves.

Shining a light on the most profound insights revealed by modern physics, Jim Al-Khalili invites us all to understand what this crucially important science tells us about the universe and the nature of reality itself. Al-Khalili begins by introducing the fundamental concepts of space, time, energy, and matter, and then describes the three pillars of modern physics - quantum theory, relativity, and thermodynamics - showing how all three must come together if we are ever to have a full understanding of reality.

What is space? It isn't a question that most of us normally stop to ask. Space is the venue of physics; it's where things exist, where they move and take shape. Yet over the past few decades, physicists have discovered a phenomenon that operates outside the confines of space and time. The phenomenon - the ability of one particle to affect another instantly across the vastness of space - appears to be almost magical.

Professor Brian Cox uncovers some of the most extraordinary natural events on Earth and in the universe and beyond. From the immensity of the universe and the roundness of Earth to the form of every single snowflake, the forces of nature shape everything we see. Pushed to extremes, the results are astonishing. In seeking to understand the everyday world, the colours, structure, behaviour and history of our home, we develop the knowledge and techniques necessary to step beyond the everyday.

In Beyond Biocentrism, acclaimed biologist Robert Lanza and astronomer Bob Berman take the listener on an intellectual thrill ride as they reexamine everything we thought we knew about life, death, the universe, and the nature of reality itself. The first step is acknowledging that our existing model of reality is looking increasingly creaky in the face of recent scientific discoveries.

In Calculating the Cosmos, Ian Stewart presents an exhilarating guide to the cosmos, from our solar system to the entire universe. He describes the architecture of space and time, dark matter and dark energy, how galaxies form, why stars implode, how everything began, and how it's all going to end. He considers parallel universes, the fine-tuning of the cosmos for life, what forms extraterrestrial life might take, and the likelihood of life on Earth being snuffed out by an asteroid.
