[15] 'Looks' means 'appears to sight', and 'looks' is throughout used as synonymous with 'appear', where the instance under discussion relates to visual perception.

[17] Cf., however, p. 87 and pp. 89-91.
[18] This is, of course, not refuted by the reminder that we see with two eyes, and that these are in different places.
[19] It is important to notice that the proper formula to express what is loosely called 'an appearance' is 'A looks or appears B', and that this cannot be analysed into anything more simple and, in particular, into a statement about 'appearances'. Even in the case of looking at the candle, there is no need to speak of two 'appearances' or 'images'. Before we discover the truth, the proper assertion is 'The body which we perceive looks as if it were two candles', and, after we discover the truth, the proper assertion is 'The candle looks as if it were in two places'.
[20] Cf. pp. 72-3, and 91.
[21] Not 'appearances'.
[22] Cf. p. 91 note.
[23] Cf. p. 82.
[24] It is assumed that there is not even plausibility in the supposition of continuity or identity between colour proper and its physical conditions in the way of light vibrations.
