Aristotle's Metaphysics was the first major study of the subject of metaphysics - in other words, an inquiry into 'first philosophy', or 'wisdom'. It differs from Physics which is concerned with the natural world: things which are subject to the laws of nature, things that move and change, are measurable. In Metaphysics, the study falls on 'being qua being' - being insofar as it is being; the causes and principles of being, the causes and principles of substances.

Two contrasting reflections by Aristotle which cover very particular ground. In 'On the Soul', Aristotle presents his view of the 'life essence' which, he argues, is possessed by living things whether plants, animals or humans. Not a 'soul' in the generally accepted Western use of the term, this 'soul', he says, is a life force that is indivisible from the organism that possesses it.

He was the father of the occult, the founder of astrology, the discoverer of alchemy. He was Hermes Trismegistus, and as the scribe of the gods of ancient Egypt, he possessed all divine knowledge... which he passed on to humanity, though only those who have been tutored in its wonders can fully understand it.In this extraordinary 1912 book, three secret initiates to his teachings - who remain anonymous to this day - share their insight with all who seek to understand the mysterious underpinnings of the universe and our relationship with it.

The Earth teems with life: in its oceans, forests, skies, and cities. Yet there's a black hole at the heart of biology. We do not know why complex life is the way it is, or, for that matter, how life first began. In The Vital Question, award-winning author and biochemist Nick Lane radically reframes evolutionary history, putting forward a solution to conundrums that have puzzled generations of scientists.

Both astonishing and prophetic, The Abolition of Man remains one of C. S. Lewis's most controversial works. Lewis sets out to persuade his audience of the ongoing importance and relevance of universal objective values, such as courage and honor, and the foundational necessity of natural law. He also makes a cogent case that a retreat from these pillars of our educational system, even if in the name of "scientism", would be catastrophic. National Review lists it as number seven on their "100 Best Nonfiction Books of the 20th Century".

"The central miracle asserted by Christians is the Incarnation. They say that God became Man. Every other miracle prepares the way for this, or results from this." This is the key statement of Miracles, in which C. S. Lewis shows that a Christian must not only accept but rejoice in miracles as a testimony of the unique personal involvement of God in his creation.

The Summa Theologica, by Thomas Aquinas, is a fundamental text in Catholic doctrine, a compendium of theology that has been studied and debated since its first publication in the 13th century. Furthermore, it has been widely regarded as one of the classics of Western philosophy, not least because, perhaps for the first time in such a systematic manner, it set out to consider the views of non-Christian figures such as Aristotle, Boethius, Muslim writers including Averroes (Ibn Rushd) and Avicenna (Ibn Sina) and the Sephardic Jewish scholar Maimonides.

Schopenhauer was just 30 when his magnum opus, Die Welt als Wille und Vorstellung, a work of considerable learning and innovation of thought, first appeared in 1818.

Much to his chagrin and puzzlement (so convinced was he of its merits), it didn't have an immediate effect on European philosophy, views and culture. It was only decades later that it was recognised as one of the major intellectual landmarks of the 19th century.

Where does DNA come from? What is consciousness? How did the eye evolve? Drawing on a treasure trove of new scientific knowledge, Nick Lane expertly reconstructs evolution's history by describing its 10 greatest inventions - from sex and warmth to death - resulting in a stunning account of nature's ingenuity.

Nobel laureate Erwin Schrödinger's What is Life? is one of the great science classics of the 20th century. A distinguished physicist's exploration of the question which lies at the heart of biology, it was written for the layman but proved one of the spurs to the birth of molecular biology and the subsequent discovery of the structure of DNA. It appears here together with "Mind and Matter", his essay investigating a relationship which has eluded and puzzled philosophers since the earliest times.

One of the most influential philosophers and theologians in the history of Western thought, St Thomas Aquinas established the foundations for much of modern philosophy of religion, and is famous for his arguments for the existence of God. In this cogent and multifaceted introduction to the great saint's work, Edward Feser argues that you cannot fully understand Aquinas' philosophy without his theology, and vice-versa. He covers Aquinas' thoughts on the soul, natural law, metaphysics, and more.

Tim Flannery’s first major book since The Weather Makers charts the history of life on our planet. Here on Earth, which draws its points of departure from Darwin and Wallace, Lovelock and Dawkins, is an extraordinary exploration of evolution and sustainability. Our success as a species has had disastrous effects on many of the Earth’s ecosystems and could lead to our downfall. But equally, Flannery argues, we are now equipped as never before to explore our true relationship with the planet on which our biological, economic and cultural futures depend.

Socrates, at 70+ years of age, defends himself against charges of corrupting the youth of Athens, atheism, and other false claims before accepting his fate and starting his final days on Earth.

Since its first appearance on the American metaphysical scene in 1908, The Kybalion has been a source of wisdom, wonder, and practical advice. Its esoteric insights, drawn from the Hermetic traditions of Ancient Egypt and Greece, present a complete philosophy of life. Now, historian and New Thought scholar Mitch Horowitz introduces this landmark work in a razor-sharp condensation that contains all the wisdom of the original.

The Emerald Tablet of Hermes & Kybalion compose two pillars of Hermetic thought. Combined here in one volume, these two works share true wisdom with those ready to receive it. The Kybalion was first published anonymously in 1908 by “The Three Initiates.” The true authorship of the work is unknown, although theories suggest it was written entirely or in part by William Walker Atkinson. The Emerald Tablet of Hermes is a short, ancient text attributed to Hermes Trismegistus. The brief Emerald Tablet has been puzzling and fascinating scholars for over 1,000 years.
