 15      I,  6 |           are either elements in the essential nature of their subjects,

 20      I,  6 |         within every genus which are essential and possessed by their respective
 21      I,  6 |             scientific knowledge are essential. For accidents are not necessary:
 22      I,  6 |     premisses are invariable but not essential, as in proofs through signs;

 24      I,  6 |              one will not know it as essential nor know its reason); but
 25      I,  7 | subject-genus whose attributes, i.e. essential properties, are revealed

 31      I,  10|              the subject genus whose essential attributes it examines; (
 32      I,  10|           the nature of the case the essential elements of demonstration
 33      I,  22|          predicates constituting the essential nature of a thing, it clearly
 34      I,  22|      possible, or in other words, if essential form is knowable, and an
 35      I,  22|    predicates constituting a thing’s essential nature must be finite in
 36      I,  22|             element constituting its essential nature, or that it is in
 37      I,  22|         subject as an element of its essential nature, is infinite. For
 38      I,  22|     coincidents, and though some are essential coincidents, others of a
 39      I,  22|              proves the inherence of essential attributes in things. Now
 40      I,  22|        things. Now attributes may be essential for two reasons: either
 41      I,  22|             they are elements in the essential nature of their subjects,
 42      I,  22|       subjects are elements in their essential nature. An example of the
 43      I,  22|              whose nature odd was an essential element: but then number
 44      I,  22|         extent. Attributes which are essential elements in the nature of
 45      I,  22|            attributes predicated are essential and these cannot be infinite,
 46      I,  23|       subjects is to be one of their essential attributes, the middle terms
 47      I,  23|               we must take a primary essential predicate-suppose it C-of
 48      I,  24|           not substance but quality, essential relatedness, or action.
 49      I,  24|            attribute through its own essential nature is itself the cause
 50      I,  28|              total subject-and their essential properties.~One science

 52      I,  33|         other hand, as regards their essential definable nature these objects
 53      I,  33|          animal is an element in the essential nature of man is knowledge;
 54      I,  33|           not as an element in man’s essential nature is opinion: man is
 55     II,  2 |          this or that as having some essential attribute or some accident-are
 56     II,  3 |        middle". Let us now state how essential nature is revealed and in
 57     II,  3 |        definition is held to concern essential nature and is in every case
 58     II,  3 |         because definition is of the essential nature or being of something,
 59     II,  3 |       evidently posit and assume the essential nature-mathematical demonstrations,
 60     II,  3 |        figure plane. Again, to prove essential nature is not the same as
 61     II,  3 |               Now definition reveals essential nature, demonstration reveals
 62     II,  3 |           before us the fact and the essential nature are not so related
 63     II,  4 |             is possible to prove the essential nature of man. Let C be
 64     II,  4 |           man. Let C be man, A man’s essential nature—two-footed animal,
 65     II,  4 |        consequently will also be the essential nature of man. Therefore
 66     II,  4 |            prove, since B too is the essential nature of man. It is, however,
 67     II,  4 |              Thus they who prove the essential nature of soul or man or
 68     II,  5 |              and yet not exhibit his essential nature or definable form?
 69     II,  5 |            the question "What is the essential nature of man?" the divider
 70     II,  6 |          peculiar" attributes of its essential nature; (2) that such and
 71     II,  6 |           the only attributes of its essential nature, and that the complete
 72     II,  7 |          shall we prove substance or essential nature? We cannot show it
 73     II,  7 |        induction proves not what the essential nature of a thing is but
 74     II,  7 |          presumably one cannot prove essential nature by an appeal to sense
 75     II,  7 |         shall we by definition prove essential nature? He who knows what
 76     II,  7 |          goat-stag" but not what the essential nature of a goat-stag is.
 77     II,  7 |     definition can prove what is the essential nature of a thing, can it
 78     II,  7 |              shall prove in defining essential nature? Triangle? In that
 79     II,  7 |            to prove either a thing’s essential nature or the meaning of
 80     II,  7 |             if it in no sense proves essential nature, is a set of words
 81     II,  7 |      anything, and that knowledge of essential nature is not to be obtained
 82     II,  8 |              definition, and whether essential nature is in any sense demonstrable
 83     II,  8 |             in none.~Now to know its essential nature is, as we said, the
 84     II,  8 |            either identical with the essential nature of the thing or distinct
 85     II,  8 |             is distinct from it, the essential nature of the thing is either
 86     II,  8 |            distinct from the thing’s essential nature and demonstration
 87     II,  8 |           proving it through another essential nature would be one way
 88     II,  8 |          would be one way of proving essential nature, because a conclusion
 89     II,  8 |              a conclusion containing essential nature must be inferred
 90     II,  8 |         through a middle which is an essential nature just as a "peculiar"
 91     II,  8 |           amount to demonstration of essential nature-it is actually a
 92     II,  8 |            exists we cannot know its essential nature. Moreover we are
 93     II,  8 |             regards awareness of its essential nature; for we have not
 94     II,  8 |              to search for a thing’s essential nature when we are unaware
 95     II,  8 |           our knowledge of a thing’s essential nature is determined by
 96     II,  8 |           aware of an element in the essential nature. Let A be eclipse,
 97     II,  8 |              we do not know what its essential nature is. But when it is
 98     II,  8 |              We have stated then how essential nature is discovered and
 99     II,  8 |           demonstrative syllogism-of essential nature, yet it is through
100     II,  8 |        demonstrative syllogism, that essential nature is exhibited. So
101     II,  8 |        conclude that neither can the essential nature of anything which
102     II,  9 |            is evident that there are essential natures which are immediate,
103     II,  9 |            through demonstration the essential nature of things which have
104     II,  10|             a quasi-demonstration of essential nature, differing from demonstration
105     II,  10|              and stating what is the essential nature of thunder; since
106     II,  10|              demonstration embodying essential nature. On the other hand
107     II,  10|           indemonstrable positing of essential nature.~We conclude then
108     II,  10|          indemonstrable statement of essential nature, or (b) a syllogism
109     II,  10|        nature, or (b) a syllogism of essential nature differing from demonstration
110     II,  10|            of a demonstration giving essential nature.~Our discussion has
111     II,  10|         sense and of what things the essential nature is demonstrable,
112     II,  10|            what things it proves the essential nature, and in what sense
113     II,  13|           have already explained how essential nature is set out in the
114     II,  13|       predicated as belonging to the essential nature are necessary and
115     II,  13|       predicated as belonging to its essential nature, triad will thus
116     II,  13|       predication of elements in its essential nature down to the last
117     II,  13|        merely towards collecting the essential nature they may be of use
118     II,  13|       omission of any element of the essential nature. Thus, if the primary
119     II,  13|              were inquiring what the essential nature of pride is, we should
120     II,  13|               Indeed, perspicuity is essential in definitions, just as
121     II,  14|          first subgenus is bird, the essential properties of every bird-and
122     II,  17|            effect is demonstrated as essential and not as inhering in virtue
123     II,  17|             the demonstration is not essential. Now it is possible to consider
