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 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.

In this beautifully written and brilliantly reasoned collection of essays, Ayn Rand throws new light on the nature of art and its purpose in human life. Once again, she demonstrates her bold originality and her refusal to let conventional ideas define her sense of the truth. Rand eloquently asserts that one cannot create art without infusing it with one's own value judgments and personal philosophy - even an attempt to withhold moral overtones only results in a deterministic or naturalistic message.

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.

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.

When and how did the universe begin? Why are we here? What is the nature of reality? Is the apparent “grand design” of our universe evidence of a benevolent creator who set things in motion—or does science offer another explanation? In The Grand Design, Stephen Hawking and Leonard Mlodinow present the most illuminating scientific thinking about these and other abiding mysteries of the universe, in nontechnical language marked by brilliance and simplicity.

There was a time when “universe” meant all there is. Everything. Yet, in recent years discoveries in physics and cosmology have led a number of scientists to conclude that our universe may be one among many. With crystal-clear prose and inspired use of analogy, Brian Greene shows how a range of different “multiverse” proposals emerges from theories developed to explain the most refined observations of both subatomic particles and the dark depths of space.

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.

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.

Mystics and sages have long maintained that there exists an interconnecting cosmic field at the roots of reality that conserves and conveys information, a field known as the Akashic record. Recent discoveries in vacuum physics show that this Akashic field is real and has its equivalent in science's zero-point field that underlies space itself. This field consists of a subtle sea of fluctuating energies from which all things arise: atoms and galaxies, stars and planets, living beings, and even consciousness.

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.

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.

Max Tegmark leads us on an astonishing journey through past, present and future, and through the physics, astronomy, and mathematics that are the foundation of his work, most particularly his hypothesis that our physical reality is a mathematical structure and his theory of the ultimate multiverse. In a dazzling combination of both popular and groundbreaking science, he not only helps us grasp his often mind-boggling theories, but he also shares with us some of the often surprising triumphs and disappointments that have shaped his life as a scientist.

Bridging the gap between the world of science and the realm of the spiritual, Wallace, a pioneer of modern consciousness research, offers a practical and revolutionary method for exploring the mind that combines the keenest insights of contemporary physics and philosophers with the time-honored meditative traditions of Buddhism.

Humans have long sought to comprehend the enormities of cosmic space and time. Here, best selling science writer Timothy Ferris tells the story of that quest. He interweaves the majestic themes of astronomy, physics, religion, and philosophy with fresh and lasting portraits of the men and women who created what has been called our society's most precious treasure - its conception of the universe at large.

Throughout history, thinkers from mathematicians to theologians have pondered the mysterious relationship between numbers and the nature of reality. In this fascinating book, Mario Livio tells the tale of a number at the heart of that mystery: phi, or 1.6180339887.... This curious mathematical relationship, widely known as "The Golden Ratio", was discovered by Euclid more than 2,000 years ago. Since then it has shown a propensity to appear in the most astonishing variety of places.

In physicist Stephen Hawking's brilliant opus, A Brief History of Time, he presented us with a bold new look at our universe, how it began, and how our old views of physics and tired theories about the creation of the universe were no longer relevant. In other words, Hawking gave us a new look at our world, our universe, and ourselves. Now, Hawking presents an even more comprehensive look at our universe, its creation, and how we see ourselves within it.
