Eckhart Tolle (German pronunciation: [ˈɛk.haʁt ˈtʰɔ.lə], English: /ˈɛ.kʰɑrt ˈtʰɒ.lə/; born 1948) is a German-born Canadian resident, best known as the author of the The Power of Now and A New Earth, which were written in English. In 2011, he was listed by the Watkins Review as the most spiritually influential person in the world. In 2008, a New York Times writer called Tolle "the most popular spiritual author in the [United States]."

Tolle says he was depressed for much of his life until he underwent, at age 29, an "inner transformation", then spent several years wandering and unemployed "in a state of deep bliss" before becoming a spiritual teacher. Later, he moved to North America where he began writing his first book, The Power of Now, which was published in 1997 and reached the New York Times Best Seller lists in 2000. Tolle settled in Vancouver, Canada, where he has lived for more than a decade.

The Power of Now and A New Earth sold an estimated three million and five million copies respectively in North America by 2009. In 2008, approximately 35 million people participated in a series of 10 live webinars with Tolle and television talk show presenter Oprah Winfrey. Tolle's books and teachings have stimulated much commentary from theologians and journalists. Tolle is not identified with any particular religion, but his work has been influenced by a wide range of spiritual teachings.

Pierre Bourdieu (1 August 1930 – 23 January 2002) was a French sociologist, anthropologist, and philosopher.

Starting from the role of economic capital for social positioning, Bourdieu pioneered investigative frameworks and terminologies such as cultural, social, and symbolic capital, and the concepts of habitus, field or location, and symbolic violence to reveal the dynamics of power relations in social life. His work emphasized the role of practice and embodiment or forms in social dynamics and worldview construction, often in dialogue and opposition to universalized Western philosophical traditions. He built upon the theories of Ludwig Wittgenstein, Maurice Merleau-Ponty, Edmund Husserl, Georges Canguilhem, Karl Marx, Gaston Bachelard, Max Weber, Émile Durkheim, Erwin Panofsky, and Marcel Mauss. A notable influence on Bourdieu was Blaise Pascal, after whom Bourdieu titled his Pascalian Meditations.

Bourdieu rejected the idea of the intellectual "prophet," or the "total intellectual," as embodied by Sartre. His best known book is Distinction: A Social Critique of the Judgment of Taste, in which he argues that judgments of taste are related to social position, or more precisely, are themselves acts of social positioning. His argument is put forward by an original combination of social theory and data from quantitative surveys, photographs and interviews, in an attempt to reconcile difficulties such as how to understand the subject within objective structures. In the process, he tried to reconcile the influences of both external social structures and subjective experience on the individual (see structure and agency).
