"Habe nun, ach! Philosophie,
Juristerei und Medizin,
Und leider auch Theologie
Durchaus studiert, mit heißem Bemühn.
Da steh ich nun, ich armer Tor!
Und bin so klug als wie zuvor;
Heiße Magister, heiße Doktor gar
Und ziehe schon an die zehen Jahr
Herauf, herab und quer und krumm
Meine Schüler an der Nase herum-
Und sehe, daß wir nichts wissen können!
Das will mir schier das Herz verbrennen.
Zwar bin ich gescheiter als all die Laffen,
Doktoren, Magister, Schreiber und Pfaffen;
Mich plagen keine Skrupel noch Zweifel,
Fürchte mich weder vor Hölle noch Teufel-
Dafür ist mir auch alle Freud entrissen,
Bilde mir nicht ein, was Rechts zu wissen,
Bilde mir nicht ein, ich könnte was lehren,
Die Menschen zu bessern und zu bekehren."
― Johann Wolfgang von Goethe, Faust:
Der Tragödie Erster Teil

"Irony is about contradictions that do not resolve into larger wholes, even dialectically, about the tension of holding incompatible things together because both or all are necessary and true. Irony is about humour and serious play. It is also a rhetorical strategy and a political method, one I would like to see more honoured within socialist-feminism." ― Donna J. Haraway, Simians, Cyborgs, and Women: The Reinvention of Nature

"Knowledge is always a legitimating idea, in the sense that assertions of knowledge always assert what is correct, what is proper, what is legitimate. If any explanatory or causal statement is accepted as knowledge, then it is accepted as an aspect of truth, and as a basis for reason, for rational action, where knowledge, truth and reason are all interrelated, legitimating ideas." ― Will Weaveright

A prepared mind is always made up; it knows what it thinks and why it thinks that. When it's time to change, it just makes itself up a different way. A really made-up mind--made up properly, knowing what it knows and on what basis it knows it--is open. People close an undecided mind because they're trying to protect those sore uncertainties from getting bumped and scraped." ― John Barnese

Falsity consists in the privation of knowledge, which inadequate, fragmentary, or confused ideas involve." ― Baruch Spinoza, Ethics

"As an empiricist I continue to think of the conceptual scheme of science as a tool, ultimately, for predicting future experience in the light of past experience. Physical objects are conceptually imported into the situation as convenient intermediaries-not by definition in terms of experience, but simply as irreducible posits comparable, epistemologically, to the gods of Homer. For my part I do, qua lay physicist, believe in physical objects and not in Homer's gods; and I consider it a scientific error to believe otherwise. But in point of epistemological footing the physical objects and the gods differ only in degree and not in kind. Both sorts of entities enter our conception only as cultural posits. The myth of physical objects is epistemologically superior to most in that it has proved more efficacious than other myths as a device for working a manageable structure into the flux of experience." ― Willard Van Orman Quine, From a Logical Point of View: Nine Logico-Philosophical Essays

"Praxeology is a theoretical and systematic, not a historical, science. Its scope is human action as such, irrespective of all environmental, accidental, and individual circumstances of the concrete acts. Its cognition is purely formal and general without reference to the material content and the particular features of the actual case. It aims at knowledge valid for all instances in which the conditions exactly correspond to those implied in its assumptions and inferences. Its statements and propositions are not derived from experience. They are, like those of logic and mathematics, a priori. They are not subject to verification or falsification on the ground of experience and facts." ― Ludwig von Mises, Human Action: A Treatise on Economics

To engage the written word means to follow a line of thought, which requires considerable powers of classifying, inference-making and reasoning. It means to uncover lies, confusions, and overgeneralizations, to detect abuses of logic and common sense. It also means to weigh ideas, to compare and contrast assertions, to connect one generalization to another. To accomplish this, one must achieve a certain distance from the words themselves, which is, in fact, encouraged by the isolated and impersonal text. That is why a good reader does not cheer an apt sentence or pause to applaud even an inspired paragraph. Analytic thought is too busy for that, and too detached." ― Neil Postman, Amusing Ourselves to Death: Public Discourse in the Age of Show Business
