26
Communication of motion by impulse or by thought equally intelligible
28
Ideas of body and spirit compared
29
Which yet serve for common converse
30
The notion of spirit involves no more difficulty in it than that of body
31
The more general our ideas are the more incomplete and partial they
32
This all accommodated to the end of speech
33
SECT
34
Men make the species Instance gold
35
Though nature makes the similitude
36
And continues it in the races of things

CHAPTER VIII
248
Instance gold
262
The names of simple ideas the least doubtful
263
And next to them simple modes
264
The most doubtful are the names of very compounded mixed modes and substances

272
As useful as to confound the sound of the letters 12 This art has perplexed religion and justice
274
And ought not to pass for learning 14 Fourthly taking them for things
275
Ideas some clear and distinct others obscure and confused 2 Clear and obscure explained by sight
276
This makes errors lasting 17 Fifthly setting them for what they cannot signify 18 V g putting them for the real essences of substances
279
Hence we think every change of our idea in substances not to change the species
280
This abuse contains two false suppositions 22 Sixthly a supposition that words have a certain and evi dent signification
281
Secondly to do it with quickness
284
2631 How mens words fail in all these

How in substances 33 How in modes and relations
287
Seventhly figurative speech also an abuse of language

First remedy to use no word without an idea 9 Secondly to have distinct ideas annexed to them in modes

304
Fifthly by constancy in their signification 27 When the variation is to be explained
