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 Origin of Species sold out on the first day of its publication in 1859. It is the major book of the 19th century and one of the most readable and accessible of the great revolutionary works of the scientific imagination. Though, in fact, little read, most people know what it says—at least they think they do. The Origin of Species was the first mature and persuasive work to explain how species change through the process of natural selection. Upon its publication, the book began to transform attitudes about society and religion.

"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.

This famous work by Lucretius is a masterpiece of didactic poetry, and it still stands today as the finest exposition of Epicurean philosophy ever written. The poem was produced in the middle of first century B.C., a period that was to witness a flowering of Latin literature unequaled for beauty and intellectual power in subsequent ages. The Latin title, De Rerum Natura, translates literally to On the Nature of Things and is meant to impress the reader with the breadth and depth of Epicurean philosophy.

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 moment a man sits on a suburban hill, gazing curiously at the stars. The next, he is whirling through the firmament, and perhaps the most remarkable of all science fiction journeys has begun. Even Stapledon's other great work, 'Last and First Men' pales in ambition next to 'Star Maker' which presents nothing less than an entire imagined history of life in the universe, encompassing billions of years.

Divine Love and Wisdom has been called the most profound work of the Enlightenment scientist and seer Emanuel Swedenborg. It demonstrates how God's love, wisdom, and humanity are reflected in creation and in ourselves, and suggests that the act of creation is not a mystery of the past, but a miracle ongoing in every instant of the present. Like a blueprint of things unseen, Divine Love and Wisdom makes visible the hidden design of the universe, as well as the qualities of its architect.

This scientific writing, which was considered to be the groundwork of evolutionary biology, presented the theory that species developed over a line of originations through a method of natural selection. It imparted evidence that the variety of life resulted from a common descent via a branching model of evolution.

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.

In The Lives of a Cell, Dr. Lewis Thomas opens up to the listener a universe of knowledge and perception that is perhaps not wholly unfamiliar to the research scientist; but the world he explores is also one of men and women, of complex interrelationships, old ironies, peculiar powers, and intricate languages that give identity to the alienated and direction to the dependent. This remarkable work offers a subtle, bold vision of humankind and the world around us - a sense of what gives life - from a writer who seems to draw grace and strength from the very substance of his subject.

The first part of this audiobook comprises several lectures to classes delivered by the present author in New York. The second part is a rather free translation of the aphorisms (sutras) of Patanjali, with a running commentary. Effort has been made to avoid technicalities as far as possible and to keep to the free and easy style of conversation.

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.
