Description : Read Now Life Witness Evolution Of The Psychotherapist by T. Byram Karasu and you can download with pub, pdf, txt, doc, and more file format with free account. in life witness: evolution of the psychotherapist, t. byram karasu demonstrates how a young therapist can become an expert clinician by transcending his own school of therapy. every young therapist attempts to perfect his skills by anchoring onto a single paradigm and becoming an expert technician of that particular school. within the first five to ten years of practice the so-called experiential evolution phase the therapist finds that no single paradigm is suitable for treating all psychopathology. the therapist thus begins to appropriate techniques from other schools of psychotherapy, and by shifting paradigms, synchronizes himself with the patient s mind. it is from this synchronization that all his techniques begin to evolve and an expert clinician can evolve into a master psychotherapist. the therapist who has transcended his school of psychotherapy now must transcend the field of psychotherapy itself. if he wants to address the patient s existential issues as well, the therapist first has to come to terms with those issues himself. after all, the therapist can take the patient only so far as he himself has come. life witness demonstrates that this formative evolution phase of a therapist encompasses a broad education in literature, philosophy, and spirituality. karasu ultimately concludes that therapists must find the meaning and purpose of life before they can cultivate an authentic self and become someone whose presence is itself therapeutic. once this occurs, all "therapeutic messages" will naturally emanate from within."

Description : Read Now Darwin S Devices by John Long and you can download with pub, pdf, txt, doc, and more file format with free account. what happens when we let robots play the game of life? the challenge of studying evolution is that the history of life is buried in the past—we can’t witness the dramatic events that shaped the adaptations we see today. but biorobotics expert john long has found an ingenious way to overcome this problem: he creates robots that look and behave like extinct animals, subjects them to evolutionary pressures, lets them compete for mates and resources, and mutates their ‘genes’. in short, he lets robots play the game of life. in darwin’s devices, long tells the story of these evolving biorobots—how they came to be, and what they can teach us about the biology of living and extinct species. evolving biorobots can replicate creatures that disappeared from the earth long ago, showing us in real time what happens in the face of unexpected environmental challenges. biomechanically correct models of backbones functioning as part of an autonomous robot, for example, can help us understand why the first vertebrates evolved them. but the most impressive feature of these robots, as long shows, is their ability to illustrate the power of evolution to solve difficult technological challenges autonomously—without human input regarding what a workable solution might be. even a simple robot can create complex behavior, often learning or evolving greater intelligence than humans could possibly program. this remarkable idea could forever alter the face of engineering, design, and even warfare. an amazing tour through the workings of a fertile mind, darwin’s devices will make you rethink everything you thought you knew about evolution, robot intelligence, and life itself.

Description : Read Now Citizen Canine by David Grimm and you can download with pub, pdf, txt, doc, and more file format with free account. dogs are getting lawyers. cats are getting kidney transplants. could they one day be fellow citizens? cats and dogs were once wild animals. today, they are family members and surrogate children. a little over a century ago, pets didn't warrant the meager legal status of property. now, they have more rights and protections than any other animal in the country. some say they're even on the verge of becoming legal persons. how did we get here—and what happens next? in this fascinating exploration of the changing status of dogs and cats in society, pet lover and award-winning journalist david grimm explores the rich and surprising history of our favorite companion animals. he treks the long and often torturous path from their wild origins to their dark days in the middle ages to their current standing as the most valued animals on earth. as he travels across the country—riding along with los angeles detectives as they investigate animal cruelty cases, touring the devastation of new orleans in search of the orphaned pets of hurricane katrina, and coming face-to-face with wolves and feral cats—grimm reveals the changing social attitudes that have turned pets into family members, and the remarkable laws and court cases that have elevated them to quasi citizens. the journey to citizenship isn't a smooth one, however. as grimm finds, there's plenty of opposition to the rising status of cats and dogs. from scientists and farmers worried that our affection for pets could spill over to livestock and lab rats to philosophers who say the only way to save society is to wipe cats and dogs from the face of the earth, the battle lines are being drawn. we are entering a new age of pets—one that is fundamentally transforming our relationship with these animals and reshaping the very fabric of society. for pet lovers or anyone interested in how we decide who gets to be a “person” in today's world, citizen canine is a must read. it is a pet book like no other.

Description : Read Now The Human Instinct by Kenneth R. Miller and you can download with pub, pdf, txt, doc, and more file format with free account. from one of america’s best-known biologists, a revolutionary new way of thinking about evolution that shows “why, in light of our origins, humans are still special” (edward j. larson, pulitzer prize–winning author of evolution). once we had a special place in the hierarchy of life on earth—a place confirmed by the literature and traditions of every human tribe. but then the theory of evolution arrived to shake the tree of human understanding to its roots. to many of the most passionate advocates for darwin’s theory, we are just one species among multitudes, no more significant than any other. even our minds are not our own, they tell us, but living machines programmed for nothing but survival and reproduction. in the human instinct, brown university biologist kenneth r. miller “confronts both lay and professional misconceptions about evolution” (publishers weekly, starred review), showing that while evolution explains how our bodies and brains were shaped, that heritage does not limit or predetermine human behavior. in fact, miller argues in this “highly recommended” (forbes) work that it is only thanks to evolution that we have the power to shape our destiny. equal parts natural science and philosophy, the human instinct makes an “absorbing, lucid, and engaging…case that it was evolution that gave us our humanity” (ursula goodenough, professor of biology at washington university in st. louis).

Description : Read Now Childhood S End by Arthur C. Clarke and you can download with pub, pdf, txt, doc, and more file format with free account. in the near future, enormous silver spaceships appear without warning over mankind’s largest cities. they belong to the overlords, an alien race far superior to humanity in technological development—and their purpose is to dominate the earth. their demands, however, are surprisingly beneficial—end war, poverty, and cruelty. their presence, rather than signaling the end of humanity, ushers in a golden age—or so it seems. but it comes at a price. without conflict, humanity ceases to work toward creative achievement, and culture stagnates. and as the years pass, it becomes more and more clear that the overlords have a hidden agenda for the evolution of the human race—that may not be as beneficial as it seems. originally published in 1953, childhood’s end is clarke’s first successful novel—and is considered a classic of science fiction literature. its dominating theme of transcendent evolution appears in many of clarke’s later works, including the space odyssey series. in 2004, the book was nominated for the retro hugo award for best novel.
