 2     II,  IV    |      intimately connected with, and essential to body; so as nowhere else
 3     II,  XXVII |             and, as it seems to me, essential to it: it being impossible

 7    III,  VI    |           contained in that idea is essential to that sort. This, though
 8    III,  VI    |             appearances.~4. Nothing essential to individuals. That essence,
 9    III,  VI    |             the thought of anything essential to any of them instantly
10    III,  VI    |          there is nothing I have is essential to me. An accident or disease
11    III,  VI    |             mine. None of these are essential to the one or the other,
12    III,  VI    |            sort, something is found essential. Let any one examine his
13    III,  VI    |            he supposes or speaks of essential, the consideration of some
14    III,  VI    |          that quality is said to be essential. So that if it be asked,
15    III,  VI    |             be asked, whether it be essential to me or any other particular
16    III,  VI    |              no; no more than it is essential to this white thing I write
17    III,  VI    |            given it, then reason is essential to it; supposing reason
18    III,  VI    |            man stands for: as it is essential to this thing I write on
19    III,  VI    |         under that species. So that essential and not essential relate
20    III,  VI    |           So that essential and not essential relate only to our abstract
21    III,  VI    |         space, then solidity is not essential to body: if others make
22    III,  VI    |         extension, then solidity is essential to body. That therefore,
23    III,  VI    |             alone, is considered as essential, which makes a part of the
24    III,  VI    |          whether it wanted anything essential? It would be absurd to ask,
25    III,  VI    |            existing wanted anything essential to it. Or could it be demanded,
26    III,  VI    |      demanded, Whether this made an essential or specific difference or
27    III,  VI    |            have no other measure of essential or specific but our abstract
28    III,  VI    |            is sufficient to make an essential difference in nature between
29    III,  VI    |             their qualities equally essential; and everything in each
30    III,  VI    |             each individual will be essential to it; or, which is more,
31    III,  VI    |       Whether obeying the magnet be essential to iron? yet I think it
32    III,  VI    | insignificant to ask, whether it be essential to the particular parcel
33    III,  VI    |             species, nothing can be essential but what is contained in
34    III,  VI    |             are so annexed as to be essential to it or inseparable from
35    III,  VI    |  inseparable from it. That which is essential belongs to it as a condition

41    III,  VI    |          rest; but whether it be an essential, a specific difference or
42    III,  VI    |           both these differences be essential or specifical, is only to
