"A Treatise Concerning the Principles of Human Knowledge" is one of Berkeley's best known works and in it Berkeley expounds upon this idea of subjective idealism, which in other words is the idea that all of reality, as far as humans are concerned, is simply a construct of the way our brains perceive and according to Berkeley no other sense of reality matters beyond that which we perceive.

    The answer has major implications, and the stakes are high. To put it in the simple terms that have come to dominate these debates, if we are free to make our own decisions, we areaccountable for what we do, and if we aren't free, we're off the hook.There are neuroscientists who claim that our decisions are made unconsciously and are therefore outside of our control and social psychologists who argue that myriad imperceptible factors influence even our minor decisions to the extent that there is no room for free will. According to philosopherAlfred R. Mele, what they point to as hard and fast evidence that free will cannot exist actually leaves much room for doubt. If we look more closely at the major experiments that free will deniers cite, we can see large gaps where the light of possibility shines through.In Free: Why Science Hasn't Disproved Free Will, Mele lays out his opponents' experiments simply and clearly, and proceeds to debunk their supposed findings, one by one, explaining how the experiments don't provide the solid evidence for which they have been touted. There is powerful evidence thatconscious decisions play an important role in our lives, and knowledge about situational influences can allow people to respond to those influences rationally rather than with blind obedience.Mele also explores the meaning and ramifications of free will. What, exactly, does it mean to have free will -- is it a state of our soul, or an undefinable openness to alternative decisions? Is it something natural and practical that is closely tied to moral responsibility? Since evidence suggeststhat denying the existence of free will actually encourages bad behavior, we have a duty to give it a fair chance.

    Looking at the efforts of philosophers from the Enlightenment through the twentieth century, Putnam traces the ways in which ethical problems arise in a historical context. Hilary Putnam's central concern is ontology--indeed, the very idea of ontology as the division of philosophy concerned with what (ultimately) exists. Reviewing what he deems the disastrous consequences of ontology's influence on analytic philosophy--in particular, the contortions it imposes upon debates about the objective of ethical judgments--Putnam proposes abandoning the very idea of ontology. He argues persuasively that the attempt to provide an ontological explanation of the objectivity of either mathematics or ethics is, in fact, an attempt to provide justifications that are extraneous to mathematics and ethics--and is thus deeply misguided.

    In addition, the wide range of Leibniz's work--letters, published papers, and fragments on a variety of philosophical, religious, mathematical, and scientific questions over a fifty-year period--heightens the challenge of preparing an edition of his writings in English translation from the French and Latin.

    Know the Faith is an attempt to present Orthodox Christianity in a way Western Christians can understand, grounding each point in Scripture and patristic theology, with comparisons to what Catholics and Protestants believe.Whether you are an Orthodox Christian seeking to explain your faith to others or an inquirer into this ancient faith, Know the Faith will help you understand and communicate the Orthodox faith as never before.

    In Timaeus, he gives a thorough account of the world in which we live, describing a cosmos composed of four elements earth, air, fire and water which combine to give existence to all things. An exploration of the origins of the universe, life and humanity, which outlines not just physical laws but also metaphysical and religious principles, it remained a paradigm of science for two thousand years. The mysterious preamble to Timaeus contains the first account in literature of Atlantis, while the fragmentary Critias, unfinished by its author, provides a spellbinding description of the lost continent's ideal society, which Critias asserts was created by the god-like children of Poseidon himself.

    It contains a brief biography of Schopenhauer, a systematic exposition of his thought, and a critical discussion of the problems to which itgives rise and of its influence on a wide range of thinkers and artists. For this new edition Magee has added three new chapters and made many minor revisions and corrections throughout. This new edition will consolidate the book's standing as the definitive study of Schopenhauer.

    These discourses, like the ones found in some of his other books, would have been transcribed by some of his listener. There are a number of surviving manuscripts of the book. The language of Shaikh 'Abd Al-Qadir's discourses is often permeated by symbolic references, metaphorical images, and poetic expressions. This style, which is characteristic of the Shaikh's discourses, reflects a number of facts. First, the Shaikh often speaks about spiritual matters that are completely unfamiliar to the layperson and which the language is incapable of describing with accuracy. These, in the Shaikh's words, are states, stations, visions, and experiences that "no eye has ever seen, no ear has ever heard, and has never occurred to any human being." Second, the Shaikh's words spring as much from his heart as from his mind, describing feelings as well as thoughts. He is forced to use common words to describe feelings that are known only to those who have had those spiritual experiences. No language is equipped enough to describe these feelings, in the same way that no words can assist in describing color to one born blind because it requires visual experience. Third, the Shaikh often speaks about secret and intimate spiritual issues that he does not want to or cannot fully disclose, thus wrapping his words in metaphors. The words of Shaikh Al-Jilani do not describe one spiritual state and are not targeted at one person. They paint a fascinating picture of a myriad of spiritual states and stations and apply to people of very different beginnings, paths, and ends. The destination is the same, but the routes are different. Also different wayfarers end their journeys at different points. What is good for someone might not good for another, and what is required of two different people might be completely different, even though both have the same goal. This is why understanding the Shaikh's words and their applications is a science in its own right. As Sufis say: "The ways to Allah are as many as the creatures." The words of the Shaikh remain as relevant to the seeker of the truth and nearness to God as they were when he uttered them almost one thousand years ago. For sure, the world has changed a lot, but man's nature has not, and the diseases of his heart remain the same. The Shaikh's words address these diseases and show man the way to salvation. His words lived a thousand years and will live to the day when this transient world is no more and is replaced by the permanent one. Like all beacons of truth, the Shaikh has been the target of attacks of the ignorant, the narrow minded, and the misguided. As happened to others who understood Islam to be about works of the heart not acts of the body, this pious servant, whose life was fully dedicated to serving his Lord, has often been accused of distorting the message of Prophet Muhammad by those who wanted to hijack Islam and turn it into a spiritless, legalistic system to serve their worldly ambitions. But, as history has been confirming everyday, the voice of truth can never be silenced and the words of wisdom will remain inerasable. It is ignorance of this fact, as well as mistaking falsehood for truth, that must have made some misguided individuals to use terrorism against the Shaikh as they bombed his shrine in Baghdad on 28th May 2007, damaging parts of it. These and similar criminals do not realize that what made great masters such as Shaikh 'Abd Al-Qadir live forever is not buildings that commemorate them or books written about them, but the teachings and examples they set that live in people's minds and love for God that they helped them develop in their hearts. This is why almost one thousand years after his departure from this world people still feel immensely honored to serve the Shaikh and his sacred cause, including making his words more accessible to people.

    But most of us who try to grapple with concepts such as reality, truth, common sense, consciousness, and society lack the rigorous training to discuss them with any confidence. John Searle brings these notions down from their abstract heights to the terra firma of real-world understanding, so that those with no knowledge of philosophy can understand how these principles play out in our everyday lives. The author stresses that there is a real world out there to deal with, and condemns the belief that the reality of our world is dependent on our perception of it.

    In all his writing, Cioran cuts to the heart of the human experience.

    Adams describes God's Debris as a thought experiment wrapped in a story. It's designed to make your brain spin around inside your skull. Imagine that you meet a very old man who you eventually realize knows literally everything. Imagine that he explains for you the great mysteries of life: quantum physics, evolution, God, gravity, light psychic phenomenon, and probability in a way so simple, so novel, and so compelling that it all fits together and makes perfect sense. What does it feel like to suddenly understand everything? You may not find the final answer to the big question, but God's Debris might provide the most compelling vision of reality you will ever read. The thought experiment is this: Try to figure out what's wrong with the old man's explanation of reality. Share the book with your smart friends, then discuss it later while enjoying a beverage.

    P. Moreland argues that Scripture, sound philosophical reasoning, and everyday experience all point to the reality of an immaterial soul.  Countering the arguments of both naturalists and Christian scholars who embrace a material-only view of humanity, Moreland demonstrates why it is both biblical and reasonable to believe humans are essentially spiritual beings.  He also describes the various components of the soul and how Christians can nurture their souls as disciples of Christ.  Moreland shows that neuroscience and the soul are not competing explanations of human activity, but that both coexist and influence one another.

    For it is not religion that is returning; rather, there is something else quite profound that is taking on increasing significance in the present: the human as a practising, training being, one that creates itself through exercises and thereby transcends itself. Rainer Maria Rilke formulated the drive towards such self-training in the early twentieth century in the imperative 'You must change your life'.In making his case for the expansion of the practice zone for individuals and for society as a whole, Sloterdijk develops a fundamental and fundamentally new anthropology. The core of his science of the human being is an insight into the self-formation of all things human. The activity of both individuals and collectives constantly comes back to affect them: work affects the worker, communication the communicator, feelings the feeler.It is those humans who engage expressly in practice that embody this mode of existence most clearly: farmers, workers, warriors, writers, yogis, rhetoricians, musicians or models. By examining their training plans and peak performances, this book offers a panorama of exercises that are necessary to be, and remain, a human being

    Here we see Augustine as a philosopher, a thinker and a budding theologian. Soliloquies is a work from Augustine's early life, shortly after his conversion, in which are visible all the seeds contained in his future writings. We see him as a person preparing for baptism, reaching for the God of truth for whom he had searched passionately. It is his personal prayer to his God of love and mercy.

    Now Blackburn offers a tour de force exploration of what he calls the most exciting and engaging issue in the whole of philosophy--the age-old war over truth.The front lines of this war are well defined. On one side are those who believe in plain, unvarnished facts, rock-solid truths that can be found through reason and objectivity--that science leads to truth, for instance. Their opponents mock this idea. They see the dark forces of language, culture, power, gender, class, ideology and desire--all subverting our perceptions of the world, and clouding our judgement with false notions of absolute truth. Beginning with an early skirmish in the war--when Socrates confronted the sophists in ancient Athens--Blackburn offers a penetrating look at the longstanding battle these two groups have waged, examining the philosophical battles fought by Plato, Protagoras, William James, David Hume, Hans-Georg Gadamer, Jacques Derrida, Michel Foucault, Richard Rorty, and many others, with a particularly fascinating look at Nietzsche. Among the questions Blackburn considers are: is science mere opinion, can historians understand another historical period, and indeed can one culture ever truly understand another.Blackburn concludes that both sides have merit, and that neither has exclusive ownership of truth. What is important is that, whichever side we embrace, we should know where we stand and what is to be said for our opponents.
