1 I, 1 | proceeds from pre-existent knowledge. This becomes evident upon 2 I, 1 | these latter make use of old knowledge to impart new, the syllogism 3 I, 1 | syllogism.~The pre-existent knowledge required is of two kinds. 4 I, 1 | as factors both previous knowledge and also knowledge acquired 5 I, 1 | previous knowledge and also knowledge acquired simultaneously 6 I, 2 | possess unqualified scientific knowledge of a thing, as opposed to 7 I, 2 | of unqualified scientific knowledge is something which cannot 8 I, 2 | productive of scientific knowledge, a syllogism, that is, the 9 I, 2 | of which is eo ipso such knowledge. Assuming then that my thesis 10 I, 2 | premisses of demonstrated knowledge must be true, primary, immediate, 11 I, 2 | productive of scientific knowledge, will not be demonstration. 12 I, 2 | be known, since to have knowledge, if it be not accidental 13 I, 2 | if it be not accidental knowledge, of things which are demonstrable, 14 I, 2 | since we possess scientific knowledge of a thing only when we 15 I, 2 | antecedently known, this antecedent knowledge being not our mere understanding 16 I, 2 | understanding of the meaning, but knowledge of the fact as well. Now " 17 I, 2 | premisses of demonstrated knowledge must be primary, I mean 18 I, 2 | precisely because of our knowledge of the latter is the effect 19 I, 2 | latter is the effect of our knowledge of the premisses. Now a 20 I, 2 | unless he has either actual knowledge of it or something better 21 I, 2 | something better than actual knowledge. But we are faced with this 22 I, 2 | demonstration has not prior knowledge; a man must believe in some, 23 I, 2 | to acquire the scientific knowledge that comes through demonstration, 24 I, 2 | must not only have a better knowledge of the basic truths and 25 I, 3 | there is no scientific knowledge. Others think there is, 26 I, 3 | them is the only form of knowledge. And since thus one cannot 27 I, 3 | know the primary premisses, knowledge of the conclusions which 28 I, 3 | them is not pure scientific knowledge nor properly knowing at 29 I, 3 | doctrine is that not all knowledge is demonstrative: on the 30 I, 3 | demonstrative: on the contrary, knowledge of the immediate premisses 31 I, 3 | that besides scientific knowledge there is its originative 32 I, 3 | which induction produces knowledge. But if we accept this extension 33 I, 3 | definition of unqualified knowledge will prove faulty; for there 34 I, 4 | object of pure scientific knowledge cannot be other than it 35 I, 4 | obtained by demonstrative knowledge will be necessary. And since 36 I, 4 | And since demonstrative knowledge is only present when we 37 I, 5 | triangles".~When, then, does our knowledge fail of commensurate universality, 38 I, 5 | and when it is unqualified knowledge? If triangle be identical 39 I, 5 | clearly we have unqualified knowledge: if on the other hand it 40 I, 5 | equilateral qua triangle; then our knowledge fails of commensurate universality. " 41 I, 6 | 6~Demonstrative knowledge must rest on necessary basic 42 I, 6 | the object of scientific knowledge cannot be other than it 43 I, 6 | is the same as to possess knowledge. For (1) popular acceptance 44 I, 6 | cause has no scientific knowledge. If, then, we suppose a 45 I, 6 | argues thus has no reasoned knowledge of the conclusion, since 46 I, 6 | again, if a man is without knowledge now, though he still retains 47 I, 6 | part; then neither had he knowledge previously. But the mediating 48 I, 6 | argument, yet he has not knowledge, and therefore had not knowledge 49 I, 6 | knowledge, and therefore had not knowledge before. Even if the link 50 I, 6 | such a condition cannot be knowledge.~When the conclusion is 51 I, 6 | up, then: demonstrative knowledge must be knowledge of a necessary 52 I, 6 | demonstrative knowledge must be knowledge of a necessary nexus, and 53 I, 6 | there is no demonstrative knowledge; for since an accident, 54 I, 6 | which produce scientific knowledge are essential. For accidents 55 I, 6 | necessarily have reasoned knowledge of a conclusion drawn from 56 I, 6 | reason); but to have reasoned knowledge of a conclusion is to know 57 I, 8 | known by strictly scientific knowledge to inhere in perishable 58 I, 9 | premisses does not constitute knowledge. Such proofs are like Bryson’ 59 I, 9 | kind. They therefore afford knowledge of an attribute only as 60 I, 9 | applicable to another genus.~Our knowledge of any attribute’s connexion 61 I, 9 | because he knows better whose knowledge is deduced from higher causes, 62 I, 9 | from higher causes, for his knowledge is from prior premisses 63 I, 9 | others or best of all, his knowledge would be science in a higher 64 I, 9 | to be sure whether one’s knowledge is based on the basic truths 65 I, 9 | attribute-the differentia of true knowledge. We think we have scientific 66 I, 9 | think we have scientific knowledge if we have reasoned from 67 I, 13| 13~Knowledge of the fact differs from 68 I, 13| of the fact differs from knowledge of the reasoned fact. To 69 I, 13| them-a necessary condition of knowledge of the reasoned fact): ( 70 I, 13| theory of the rainbow. Here knowledge of the fact is within the 71 I, 13| the natural philosopher, knowledge of the reasoned fact within 72 I, 14| the primary condition of knowledge. Thirdly, the first is the 73 I, 14| which enables us to pursue knowledge of the essence of a thing. 74 I, 14| conclusion is possible, and knowledge of a thing’s essence must 75 I, 14| the primary condition of knowledge.~ 76 I, 16| Ignorance-defined not as the negation of knowledge but as a positive state 77 I, 18| corresponding portion of knowledge, and that, since we learn 78 I, 18| or by demonstration, this knowledge cannot be acquired. Thus 79 I, 18| be objects of scientific knowledge, because neither can universals 80 I, 18| neither can universals give us knowledge of them without induction, 81 I, 22| have something better than knowledge, nor can one know them without 82 I, 22| have something better than knowledge of it, then we shall not 83 I, 22| shall not have scientific knowledge of the consequent. Therefore, 84 I, 22| not something better than knowledge of them, we cannot through 85 I, 23| immediate premiss, and in the knowledge that demonstration gives 86 I, 24| demonstration which gives us greater knowledge (for this is the ideal of 87 I, 24| demonstration), and we have greater knowledge of a particular individual 88 I, 24| applies that the greater knowledge is his who knows the subject 89 I, 24| universally has greater knowledge of it as it in fact is than 90 I, 24| as then only having full knowledge of the reason why he came.~ 91 I, 24| this is the means to full knowledge in the case of final causes 92 I, 24| the other causes also full knowledge is attained when an attribute 93 I, 24| knowledge-but at this point our knowledge has become commensurately 94 I, 25| known, where they are fewer knowledge will be more speedily acquired, 95 I, 27| 27~The science which is knowledge at once of the fact and 96 I, 30| 30~There is no knowledge by demonstration of chance 97 I, 31| 31~Scientific knowledge is not possible through 98 I, 31| cannot obtain scientific knowledge by the act of perception: 99 I, 31| not (as some say) possess knowledge of it; for perception must 100 I, 31| particular, whereas scientific knowledge involves the recognition 101 I, 31| than themselves universal knowledge is more precious than sense-perceptions 102 I, 31| Hence it is clear that knowledge of things demonstrable cannot 103 I, 31| possession of scientific knowledge through demonstration. Nevertheless 104 I, 32| the basic truths of all knowledge are within one genus, special 105 I, 33| 33~Scientific knowledge and its object differ from 106 I, 33| opinion in that scientific knowledge is commensurately universal 107 I, 33| be otherwise, scientific knowledge clearly does not concern 108 I, 33| knowledge-nor of indemonstrable knowledge, which is the grasping of 109 I, 33| necessary is the object of knowledge.~In what sense, then, can 110 I, 33| object of both opinion and knowledge? And if any one chooses 111 I, 33| why should not opinion be knowledge? For he that knows and he 112 I, 33| he that opines also has knowledge.~The truth perhaps is that 113 I, 33| will have not opinion but knowledge: if on the other hand he 114 I, 33| opinion and not genuine knowledge; and his opinion, if obtained 115 I, 33| The object of opinion and knowledge is not quite identical; 116 I, 33| identity of the objects of knowledge and opinion is similar. 117 I, 33| and opinion is similar. Knowledge is the apprehension of, 118 I, 33| essential nature of man is knowledge; the apprehension of animal 119 I, 33| otherwise-an impossibility. Knowledge and opinion of the same 120 II, 2 | these questions that our knowledge consists.~Now when we ask 121 II, 3 | that to have scientific knowledge of the demonstrable is identical 122 II, 3 | attribute or accident-did we get knowledge of it. Again, if to define 123 II, 3 | to define is to acquire knowledge of a substance, at any rate 124 II, 3 | there is a single scientific knowledge. Hence, since to know the 125 II, 3 | demonstration will give knowledge of the demonstrable.~Moreover, 126 II, 5 | involve inference; if it gives knowledge, it gives it in another 127 II, 7 | proves anything, and that knowledge of essential nature is not 128 II, 8 | often as we have accidental knowledge that the thing exists, we 129 II, 8 | we have not got genuine knowledge even of its existence, and 130 II, 8 | follows that the degree of our knowledge of a thing’s essential nature 131 II, 11| think we have scientific knowledge when we know the cause, 132 II, 19| to produce, demonstrative knowledge, since it is the same as 133 II, 19| is the developed state of knowledge of them is made clear by 134 II, 19| already said that scientific knowledge through demonstration is 135 II, 19| is or is not scientific knowledge of both; or scientific knowledge 136 II, 19| knowledge of both; or scientific knowledge of the latter, and of the 137 II, 19| former a different kind of knowledge; and, further, whether the 138 II, 19| the developed states of knowledge are not innate but come 139 II, 19| a basis of pre-existent knowledge? For that is impossible, 140 II, 19| in us if we are without knowledge of them to the extent of 141 II, 19| come to be have either no knowledge at all outside the act of 142 II, 19| act of perceiving, or no knowledge of objects of which no impression 143 II, 19| of the craftsman and the knowledge of the man of science, skill 144 II, 19| conclude that these states of knowledge are neither innate in a 145 II, 19| from other higher states of knowledge, but from sense-perception. 146 II, 19| accurate than scientific knowledge, whereas primary premisses 147 II, 19| demonstrations, and all scientific knowledge is discursive. From these 148 II, 19| there will be no scientific knowledge of the primary premisses, 149 II, 19| be truer than scientific knowledge, it will be intuition that 150 II, 19| consequently, scientific knowledge of scientific knowledge. 151 II, 19| knowledge of scientific knowledge.If, therefore, it is the 152 II, 19| originative source of scientific knowledge. And the originative source
