whole book or two in some instances, and Kierkegaard, or another pseudonym, critiques that position. For example, the author, Johannes Climacus is not a Christian and he argues from a non-Christian viewpoint. Anti-Climacus, as mentioned earlier, is a Christian to a high degree and he argues from a devout Christian viewpoint. Kierkegaard places his beliefs in-between these two authors. Most of Kierkegaard's later philosophical and religious writings from 1846 to 1855 were written and authored by himself, and he assigned no pseudonyms to these works. Subsequently, these works are considered by most scholars to reflect Kierkegaard's own beliefs. Where appropriate, this article will mention the respective author, pseudonymous or not. Themes in his philosophy Alienation Alienation is a term philosophers apply to a wide variety of phenomena, including any feeling of separation from, and discontent with, society; feeling that there is a moral breakdown in society; feelings of powerlessness in the face of the solidity of social institutions; the impersonal, dehumanised nature of large-scale and bureaucratic social organisations. Kierkegaard recognizes and accepts the notion of alienation, although he phrases it and understands it in his own distinctly original terms. For Kierkegaard, the present age is a reflective age—one that values objectivity and thought over action, lip-service to ideals rather than action, discussion over action, publicity and advertising over reality, and fantasy over the real world. For Kierkegaard, the meaning of values has been removed from life, by lack of finding any true and legitimate authority. Instead of falling into any claimed authority, any "literal" sacred book or any other great and lasting voice, self-aware humans must confront an existential uncertainty. Humanity has lost meaning because the accepted criterion of reality and truth is ambiguous and subjective thought—that which cannot be proven with logic, historical research, or scientific analysis. Humans cannot think out choices in life, we must live them; and even those choices that we often think about become different once life itself enters into the picture. For Kierkegaard, the type of objectivity that a scientist or historian might use misses the point—humans are not motivated and do not find meaning in life through pure objectivity. Instead, they find it through passion, desire, and moral and religious commitment. These phenomena are not objectively provable—nor do they come about through any form of analysis of the external world; they come about through a direct relationship between one and the external world.
