 A sign is indicative, they say, if it signifies that of which it is a sign not by having been observed evidently together with the thing it signifies but from its proper nature and constitution (as bodily movements are signs of the soul). That is why they also define this sign as follows: An indicative sign is a pre-antecedent statement in a sound conditional, revelatory of the consequent. There being two different sorts of signs…we argue not against all signs but only against indicative signs, which seem to be a fiction of the Dogmatists. For recollective signs are found convincing by everyday life: seeing smoke, someone diagnoses fire, having observed a scar, he says that a wound was inflicted. (SE-OS: 93: 101, 102)
