Summary

Throughout history, some books have changed the world. They have transformed the way we see ourselves-and each other. They have inspired debate, dissent, war and revolution. They have enlightened, outraged, provoked and comforted. They have enriched lives-and destroyed them. Now, Penguin brings you the works of the great thinkers, pioneers, radicals and visionaries whose ideas shook civilization, and helped make us who we are. Penguin's Great Ideas series features twelve groundbreaking works by some of history's most prodigious thinkers, and each volume is beautifully packaged with a unique type-drive design that highlights the bookmaker's art. Offering great literature in great packages at great prices, this series is ideal for those readers who want to explore and savor the Great Ideas that have shaped the world. Few ancient works have been as influential as the Meditations of Marcus Aurelius, philosopher and emperor of Rome (A.D. 161180). A series of spiritual exercises filled with wisdom, practical guidance, and profound understanding of human behavior, it remains one of the greatest works of spiritual and ethical reflection ever written. Marcus's insights and advice-on everything from living in the world to coping with adversity and interacting with others-have made the Meditations required reading for statesmen and philosophers alike, while generations of ordinary readers have responded to the straightforward intimacy of his style. For anyone who struggles to reconcile the demands of leadership with a concern for personal integrity and spiritual well-being, the Meditations remains as relevant now as it was two thousand years ago.

Struggle for Existence

Nothing is easier than to admit in words the truth of the universal struggle for life, or more difficult - at least I have found it so - than constantly to bear this conclusion in mind. Yet unless it be thoroughly engrained in the mind, I am convinced that the whole economy of nature, with every fact on distribution, rarity, abundance, extinction, and variation, will be dimly seen or quite misunderstood. We behold the face of nature bright with gladness, we often see superabundance of food; we do not see, or we forget, that the birds which are idly singing round us mostly live on insects or seeds, and are thus constantly destroying life; or we forget how largely these songsters, or their eggs, or their nestlings, are destroyed by birds and beasts of prey; we do not always bear in mind, that though food may be now superabundant, it is not so at all seasons of each recurring year.

I should premise that I use the term Struggle for Existence in a large and metaphorical sense, including dependence of one being on another, and including (which is more important) not only the life of the individual, but success in leaving progeny. Two canine animals in a time of dearth, may be truly said to struggle with each other which shall get food and live.
