# Epistemology

Epistemology is derived from the Greek words episteme (knowledge) and logos (word/speech) is the branch of philosophy that deals with the nature, origin and scope of knowledge.

## Quotes

* Since the word "knowledge" occurs in my general title... I am going to be talking about epistemology, although I prefer to use the eighteenth-century, indeed, medieval phrase, "natural philosophy." ...that enterprise of the human mind which attempts to trace lawfulness to nature, dead and living, but which is not directed to specific inquiries into how this or that law works. Philosophy in the sense in which I practice it, natural philosophy, is concerned with lawfulness rather than with laws and the general nature of laws rather than with the specific structure of this or that law.
** Jacob Bronowski, The Origins of Knowledge and Imagination (1978)
* The central place of epistemology in modern philosophy is no accident... Knowledge was not a problem for the ruling philosophy of the Middle Ages; that the whole world which man's mind seeks to understand is intelligible to it was explicitly taken for granted. That people subsequently came to consider knowledge a problem implies that they had been led to accept certain different beliefs about the nature of man and about the things which he tries to understand.
** Edwin Arthur Burtt, The Metaphysical Foundations of Modern Physical Science (1925)
* Western civilization, unfortunately, does not link knowledge and morality but rather, it connects knowledge and power and makes them equivalent. Today with an information "superhighway" now looming on the horizon, we are told that a lack of access to information will doom people to a life of meaninglessness — and poverty. As we look around and observe modern industrial society, however, there is no question that information, in and of itself, is useless and that as more data is generated, ethical and moral decisions are taking on a fantasy dimension in which a "lack of evidence to indict" is the moral equivalent of the good deed.
** Vine Deloria Jr., Foreword to Words of Power: Voices from Indian America (1994)
* Thinking is another attribute of the soul; and here I discover what properly belongs to myself. This alone is inseparable from me. I am—I exist: this is certain.
** René Descartes, Meditations on First Philosophy (1641)
* No more useful inquiry can be proposed than that which seeks to determine the nature and the scope of human knowledge. ... This investigation should be undertaken once at least in his life by anyone who has the slightest regard for truth, since in pursuing it the true instruments of knowledge and the whole method of inquiry come to light. But nothing seems to me more futile than the conduct of those who boldly dispute about the secrets of nature ... without yet having ever asked even whether human reason is adequate to the solution of these problems.

* Cogito, ergo sum.
** I think, therefore I am.
*** René Descartes, Principia philosophiae (1644)
* Is it easier to know what our culture’s epistemic norms are in terms of which it is to be determined whether or not giraffes are taller than ants than it is to know that giraffes are taller than ants? Is our knowledge concerning the identity of those norms to be construed on a realist model, or must we rather consult our culture’s epistemic norms in order to use them to figure out the identity of those norms? If the former, why is it that we can have objective knowledge concerning the identity of our culture’s epistemic norms when we can’t have it with regard to the relative height of giraffes and ants? And if the latter, how is an infinite regress to be avoided?
** David Detmer, criticizing Richard Rorty’s pragmatism in Challenging Postmodernism (New York: 2003), p. 130
* Can science ever be immune from experiments conceived out of prejudices and stereotypes, conscious or not? (Which is not to suggest that it cannot in discrete areas identify and locate verifiable phenemonena in nature.) I await the study that says lesbians have a region of the hypothalamus that resembles straight men and I would not be surprised if, at this very moment, some scientist somewhere is studying brains of deceased Asians to see if they have an enlarged "math region" of the brain.
** Kay Diaz, Z (Dec. 1992)
* How does it happen that a properly endowed natural scientist comes to concern himself with epistemology? Is there no more valuable work in his specialty? I hear many of my colleagues saying, and I sense it from many more, that they feel this way. I cannot share this sentiment. When I think about the ablest students whom I have encountered in my teaching, that is, those who distinguish themselves by their independence of judgment and not merely their quick-wittedness, I can affirm that they had a vigorous interest in epistemology. They happily began discussions about the goals and methods of science, and they showed unequivocally, through their tenacity in defending their views, that the subject seemed important to them. Indeed, one should not be surprised at this.

* Science can only be comprehended epistemologically, which means as one category of possible knowledge, as long as knowledge is not equated either effusively with the absolute knowledge of a great philosophy or blindly with scientistic self-understanding of the actual business of research.
** Jürgen Habermas Knowledge and human Interests (1971) p. 4.
* Both social and biosocial factors are necessary to interpret crosscultural studies, with the general proviso that one's research interest determines which elements, in what combinations, are significant for the provision of understanding.
** Gilbert Herdt, "Bisexuality and the Causes of Homosexuality: The Case of the Sambia" (1998)
* The fruitfulness of knowledge indeed plays a role in its claim to truth, but the fruitfulness in question is to be understood as intrinsic to the science and not as usefulness for ulterior purposes.
** Max Horkheimer, "Notes on Science and the Crisis," Critical Theory: Selected Essays (1995) p. 3.
* Science may be in the interest of the ruling class, after all, but it is still responsive to epistemic norms, and so anyone with epistemic interests has reason to accept science. Ideologies, by contrast, have their genesis explained solely by their capacity to further the interests of the ruling class.
** Brian Leiter, “Morality Critics,” The Oxford Handbook of Continental Philosophy (2007)
* A modern theory of knowledge which takes account of the relational as distinct from the merely relative character of all historical knowledge must start with the assumption that there are spheres of thought in which it is impossible to conceive of absolute truth existing independently of the values and position of the subject and unrelated to the social context.
** Karl Mannheim Ideology and Utopia (1929)
* If man has learned to see and know what really is, he will act in accordance with truth, Epistemology is in itself ethics, and ethics is epistemology.
** Herbert Marcuse, One-Dimensional Man (1964)
* I keep having the same experience and keep resisting it every time. I do not want to believe it although it is palpable: the great majority of people lack an intellectual conscience. Indeed, it has often seemed to me as if anyone calling for an intellectual conscience were as lonely in the most densely populated cities as if he were in a desert. Everybody looks at you with strange eyes and goes right on handling his scales, calling this good and that evil. Nobody even blushes when you intimate that their weights are underweight; nor do people feel outraged; they merely laugh at your doubts. I mean: the great majority of people does not consider it contemptible to believe this or that and to live accordingly, without first having given themselves an account of the final and most certain reasons pro and con, and without even troubling themselves about such reasons afterward: the most gifted men and the noblest women still belong to this "great majority." But what is goodheartedness, refinement, or genius to me, when the person who has these virtues tolerates slack feelings in his faith and judgments and when he does not account the desire for certainty as his inmost craving and deepest distress—as that which separates the higher human beings from the lower.
** Friedrich Nietzsche, The Gay Science (1882), Section 2
* Physics is mathematical, not because we know so much about the physical world, but because we know so little: it is only its mathematical properties that we can discover. For the rest our knowledge is negative.
** Bertrand Russell, An Outline of Philosophy (1927)
* Science is what we know, and philosophy is what we don't know.
** Bertrand Russell Unpopular Essays (1950)
* The genius of culture is to create an ontological system so compelling that what is inside and outside of a person are viewed as of a piece, no seams and patches noticeable.
** Richard Shweder, "Cultural psyschology-What is it?" Cultural Psychology (1990)
* For philosophy, it is supposed by vast numbers of students and teachers of the subject, has for its goal philosophical knowledge, and indeed, even certain knowledge. It is presupposed, therefore, that there is such a thing as philosophical knowledge, and there are even men who think themselves the possessors of at least some of it...I shall maintain that there simply is no such thing as philosophical knowledge, nor any philosophical way of knowing anything, and defend the humble point that philosophy is indeed the love of wisdom.
** Richard Taylor, "Dare to be Wise" The Review of Metaphysics (June, 1968), p. 615
* Hegel’s lack of charity toward the instrument metaphor is not arbitrary. It represents his disenchantment with the assumption that knowledge is power and that method is the means to this end. ... Descartes’ conception of method, like Bacon’s, is linked to this idea of knowledge as an instrument of power. ... The same could be said of Locke. Hegel can rightly claim that the instrument metaphor pervades the epistemological tradition he is seeking to transcend.
** Merold Westphal, History and Truth in Hegel’s Phenomenology (1979), pp. 3-4
* A further turn is to be found in some "unmasking" accounts of natural science, which aim to show that its pretensions to deliver the truth are unfounded, because of social forces that control its activities. Unlike the case of history, these do not use truths of the same kind; they do not apply science to the criticism of science. They apply the social sciences, and typically depend on the remarkable assumption that the sociology of knowledge is in a better position to deliver truth about science than science is to deliver truth about the world.
