| Ludwig von Mises | Man thinks not only for the sake of thinking, but also in order to act. | Epistemological Problems of Economics | p. 37 | Action |
| Ludwig von Mises | Art is nothing more than a faltering and inadequate attempt to express what has been thus experienced and to give some form to its content. The work of art captures not the experience, but only what its creator has been able to express of the experience. | Epistemological Problems of Economics | p. 45 | Arts |
| Ludwig von Mises | The most primitive work of art also can express the strongest experience, and it speaks to us, if only we let it. | Epistemological Problems of Economics | p. 46 | Arts |
| Ludwig von Mises | A work of art is an attempt to experience the universe as a whole. One cannot analyze or dissect it into parts and comment on it without destroying its intrinsic character. | Epistemological Problems of Economics | p. 136 | Arts |
| Ludwig von Mises | Through all the changes in the prevailing system of social stratification, moral philosophers continued to hold fast to the fundamental idea of Ciceros doctrine that making money is degrading. | Epistemological Problems of Economics | p. 194 | Bourgeoisie |
| Ludwig von Mises | In life everything is continually in flux. | Epistemological Problems of Economics | p. 108 | Change |
| Ludwig von Mises | To the man who adopts the scientific method in reflecting upon the problems of human action, liberalism must appear as the only policy that can lead to lasting well-being for himself, his friends, and his loved ones, and, indeed, for all others as well. | Epistemological Problems of Economics | p. 39 | Classical Liberalism |
| Ludwig von Mises | It is not mankind, the state, or the corporative unit that acts, but individual men and groups of men, and their valuations and their action are decisive, not those of abstract collectivities. | Epistemological Problems of Economics | p. 153 | Collectivism |
| Ludwig von Mises | The collectivists idolize only the one true church, only the great nation . . . only the true state; everything else they condemn. For that reason all collectivists doctrines are harbingers of irreconcilable hatred and war to the death. | Epistemological Problems of Economics | p. 42 | Collectivism |
| Ludwig von Mises | We owe the origin and development of human society and, consequently, of culture and civilization, to the fact that work performed under the division of labor is more productive than when performed in isolation. | Epistemological Problems of Economics | p. 110 | Culture |
| Ludwig von Mises | The specific experience with which economics and economic statistics are concerned always refers to the past. It is history, and as such does not provide knowledge about a regularity that will manifest itself also in the future. | Epistemological Problems of Economics | p. xiv | Econometrics |
| Ludwig von Mises | Without the aid of monetary calculation, bookkeeping, and the computation of profit and loss in terms of money, technology would have had to confine itself to the simplest, and therefore the least productive, methods. | Epistemological Problems of Economics | p. 157 | Economic Calculation |
| Ludwig von Mises | Monetary calculation is not the calculation, and certainly not the measurement, of value. Its basis is the comparison of the more important and the less important. It is an ordering according to rank, an act of grading, and not an act of measuring. | Epistemological Problems of Economics | p. 160 | Economic Calculation |
| Ludwig von Mises | Economic progress is the work of the savers, who accumulate capital, and of the entrepreneurs, who turn capital to new uses. The other members of society, of course, enjoy the advantages of progress, but they not only do not contribute anything to it; they even place obstacles in its way. | Epistemological Problems of Economics | p. 228 | Economic Progress |
| Ludwig von Mises | Everything that we say about action is independent of the motives that cause it and of the goals toward which it strives in the individual case. | Epistemological Problems of Economics | p. 34 | Economics |
| Ludwig von Mises | In all ages the pioneer in scientific thought has been a solitary thinker. But never has the position of the scientist been more solitary than in the field of modern economics. | Epistemological Problems of Economics | p. 202 | Economics |
| Ludwig von Mises | New experience can force us to discard or modify inferences we have drawn from previous experience. | Epistemological Problems of Economics | p. 27 | Experience |
| Ludwig von Mises | Even knowledge of the laws of nature does not make action free. It is never able to attain more than definite, limited ends. It can never go beyond the insurmountable barriers set for it. And even within the sphere allowed to it, it must always reckon with the inroads of uncontrollable forces, with fate. | Epistemological Problems of Economics | p. 198 | Fate |
| Ludwig von Mises | What counts is not the data, but the mind that deals with them…. Galileo was certainly not the first to observe the swinging motion of the chandelier in the cathedral at Pisa. | Epistemological Problems of Economics | p. 71 | Genius |
| Ludwig von Mises | It is merely the routine of scientific procedure that can be taught and presented in textbooks. The power to accomplish feats of scientific achievement can be awakened only in one who already possesses the necessary intellectual gifts and strength of character. | Epistemological Problems of Economics | pp. 7172 | Genius |
| Ludwig von Mises | History makes one wise, but not competent to solve concrete problems. | Epistemological Problems of Economics | p. xxiii | History |
| Ludwig von Mises | No one can escape the influence of a prevailing ideology. | Epistemological Problems of Economics | p. 197 | Ideology |
| Ludwig von Mises | The infant industries argument advanced in favor of protective tariffs represents a hopeless attempt to justify such measures on a purely economic basis, without regard to political considerations. | Epistemological Problems of Economics | p. 223 | Infant Industries |
| Ludwig von Mises | Only the literati are enthusiastic about poverty, i.e., the poverty of others. The rest of mankind, however, prefer prosperity to misery. | Epistemological Problems of Economics | p. 92 | Intellectuals |
| Ludwig von Mises | The educated classes are possessed by the idea that in the social domain anything can be accomplished if only one applies enough force and is sufficiently resolute. | Epistemological Problems of Economics | p. 200 | Intellectuals |
| Ludwig von Mises | Every new theory encounters opposition and rejection at first. | Epistemological Problems of Economics | p. 184 | Intellectuals |
| Ludwig von Mises | Cognition is furthered only by clarity and distinctness, never by compromises. | Epistemological Problems of Economics | p. 206 | Knowledge |
| Ludwig von Mises | It is not to be denied that the loftiest theme that human thought can set for itself is reflection on ultimate questions. Whether such reflection can accomplish anything is doubtful. | Epistemological Problems of Economics | p. 49 | Metaphysics |
| Ludwig von Mises | One may hold poets, prophets, or promulgators of new values in higher esteem than scientists. But in no case is one free to confound these two fundamentally different functions. | Epistemological Problems of Economics | p. 49 | Metaphysics |
| Ludwig von Mises | Metaphysics and science perform different functions. They cannot, therefore, adopt the same procedures, nor are they alike in their goals. | Epistemological Problems of Economics | p. 49 | Metaphysics |
