Logic History

Kierkegaard wasn't really a philosopher in the academic sense. Yet he produced what many people expect of philosophy. His subject was the individual and his or her existence, the "existing being." In Kierkegaard's view, this purely subjective entity lay beyond the reach of reason, logic, philosophical systems, theology, or even "the pretenses of psychology." Nonetheless, it was the source of all these subjects. The branch of philosophy to which Kierkegaard gave birth has come to be known as existentialism.

With Friedrich Nietzsche, philosophy was dangerous not only for philosophers but for everyone. His ideas presaged a collective madness that had horrific consequences in Europe in the early 1900s. Though his philosophy is more one of aphorisms than a system, it is brilliant, persuasive, and incisive. His major concept is the will to power, which he saw as the basic impulse for all our acts. Christianity he saw as a subtle perversion of this concept, thus Nietzsche's famous pronouncement, "God is dead."

Rene Descartes spent most of his childhood in solitude, a situation that also came to characterize his adult life. Fortunately, these countless lonely hours helped Descartes produce the declaration that changed all philosophy: "I think, therefore I am." Eventually convincing himself to doubt and disregard sensory knowledge, Descartes found he could prove his existence through his thoughts. This internal information, he believed, was the true reality and external forces were hopelessly deceiving.

Immanuel Kant taught and wrote prolifically about physical geography yet never traveled further than forty miles from his home in Kvnigsberg. How appropriate it is then that in his philosophy he should deny that all knowledge was derived from experience. He insisted that all experience must conform to knowledge. According to Kant, space and time are subjective; along with various "categories," they help us to see the phenomena of the world, though never its true reality.

One of our greatest philosophers and scientists of the mind asks where the self comes from - and how our selves can exist in the minds of others. I Am a Strange Loop argues that the key to understanding selves and consciousness is the "strange loop" - a special kind of abstract feedback loop inhabiting our brains. The most central and complex symbol in your brain is the one called "I". The "I" is the nexus in our brain, one of many symbols seeming to have free will and to have gained the paradoxical ability to push particles around, rather than the reverse.

David Hume reduced philosophy to ruins: he denied the existence of everything, except our actual perceptions themselves. I alone exist, he argued, and the world is nothing more than part of my consciousness. Yet we know that the world remains, and we go on as before. What Hume expressed was the status of our knowledge about the world, a world in which neither religion nor science is certain.

In Rousseau we encounter a walking ego, naked sensibility. Feeling triumphs over intellectual argument in his works, which are both deeply stirring and deeply inconsistent. Yet while his contemporaries Kant and Hume may have been superior academic philosophers, the sheer power of Rousseau's ideas was unequaled in his time. It was he who encouraged the introduction of both liberty and irrationality into the public domain.

For more than a century, from 1900 to 2006, campaigns of nonviolent resistance were more than twice as effective as their violent counterparts in achieving their stated goals. Authors Erica Chenoweth and Maria J. Stephan detail the factors enabling such campaigns to succeed and, sometimes, causing them to fail.

At the beginning of Nonzero, Robert Wright sets out to "define the arrow of the history of life, from the primordial soup to the World Wide Web." Twenty-two chapters later, after a sweeping and vivid narrative of the human past, he has succeeded and has mounted a powerful challenge to the conventional view that evolution and human history are aimless.

Does time exist? What is infinity? Why do mirrors reverse left and right but not up and down? In this scintillating collection, Holt explores the human mind, the cosmos, and the thinkers who’ve tried to encompass the latter with the former. With his trademark clarity and humor, Holt probes the mysteries of quantum mechanics, the quest for the foundations of mathematics, and the nature of logic and truth. Along the way, he offers intimate biographical sketches of celebrated and neglected thinkers, from the physicist Emmy Noether to the computing pioneer Alan Turing and the discoverer of fractals, Benoit Mandelbrot.

All effective debaters, whether they know it or not, employ Aristotle's 3 basic principles of effective argument that form the spine of Rhetoric. In Poetics, Aristotle draws a dramatic distinction between poetry and history. This collection also includes Aristotle's body of work that has come to be identified as Logic.

In our ever-more-polarized society, there's at least one thing we still agree on: The world is overrun with misinformation, faulty logic, and the gullible followers who buy into it all. Of course, we're not among them - are we? Scientist David Robert Grimes is on a mission to expose the logical fallacies and cognitive biases that drive our discourse on a dizzying array of topics - from vaccination to abortion, 9/11 conspiracy theories to dictatorial doublespeak, astrology to alternative medicine, and wrongful convictions to racism.

Charles Sanders Peirce is perhaps the greatest philosophical mind to emerge from the United States. He was hugely influential on William James, Alfred North Whitehead, and many other eminent thinkers. This small volume includes two famous essays by Peirce, "The Fixation of Belief" and "Questions Concerning Certain Faculties Claimed for Man." Also included is a short, intellectual biography of Peirce which focuses on his many contributions to science and philosophy. Chosen and very slightly edited by Professor David Christopher Lane, PhD.

This fresh and exciting approach to science, skepticism, and critical thinking will enlighten and inspire listeners of all ages. With a mix of wit and wisdom, it challenges everyone to think like a scientist, embrace the skeptical life, and improve their critical thinking skills. Think shows you how to better navigate through the maze of biases and traps that are standard features of every human brain.

On June 22, 1936, the philosopher Moritz Schlick was on his way to deliver a lecture at the University of Vienna when Johann Nelböck, a deranged former student of Schlick's, shot him dead on the university steps. Some Austrian newspapers defended the madman, while Nelböck himself argued in court that his onetime teacher had promoted a treacherous Jewish philosophy. David Edmonds traces the rise and fall of the Vienna Circle - an influential group of brilliant thinkers led by Schlick.

Popular culture in America today is dominated by the left. But so many young conservatives in America want to stand up for their beliefs in their classrooms, at their jobs, with their friends, or on social media, but they don’t have the tools to do so. In How to Win Friends and Influence Enemies, Will Witt arms Gen Zs and millennials with the knowledge and skills to combat the leftist narrative they hear every day.

By explaining how the human brain works and outing its most irrational processes, this book provides the thinking tools that will help you make better decisions, ask the right questions (at the right time), know what to look for when evaluating information, and understand how your own brain subconsciously clouds your judgment. Think you're too smart to be easily misled? Harrison summarizes scientific research showing how easily even intelligent and well-educated people can be fooled.

In very recent times humanity has learnt a vast amount about the universe, the past and itself. But through our remarkable successes in acquiring knowledge we have learned how much we have yet to learn: the science we have, for example, addresses just five per cent of the universe, pre-history is still being revealed, with thousands of historical sites yet to be explored, and the new neurosciences of mind and brain are just beginning.
