"admit of being observed in conjunction with the thing signified (for the naturally non-evident object is, from the start, imperceptible and therefore cannot be observed along with any of the things apparent), but entirely of its own nature and constitution, all but uttering its voice aloud, it is said to signify that whereof it is indicative."

''Outlines of Pyrrhonism'' Book II Section 317
The commemorative sign represents something that has previously been experienced in conjunction with its object. Consequently, the object of a commemorative sign can be described empirically.
"Thus the commemorative sign, when observed in conjunction with the thing signified in a clear perception, brings us as soon as it is presented and when the thing signified has become non-evident, to a recollection of the thing observed along with it and now no longer clearly perceived - as in the case of smoke and fire; for as we have often observed these to be connected with each other, as soon as we see the one-that is to say, smoke-we recall the other-that is to say, the unseen fire."

philosophy rejects the validity of indicative signs as they are non-empirical. It recognizes only commemorative signs.
Christianity
St. Augustine was the first man who synthesized the classical and Hellenistic theories of signs. For him a sign is a thing which is used to signify other things and to make them come to mind (''
De Doctrina Christiana'' (hereafter DDC) 1.2.2; 2.1.1). The most common signs are spoken and written words (DDC 1.2.2; 2.3.4-2.4.5). Although God cannot be fully expressible, Augustine gave emphasis to the possibility of God’s communication with humans by signs in Scripture (DDC 1.6.6). Augustine endorsed and developed the classical and Hellenistic theories of signs. Among the mainstream in the theories of signs, i.e., that of Aristotle and that of Stoics, the former theory filtered into the works of Cicero (106-43 BC, ''De inventione rhetorica'' 1.30.47-48) and Quintilian (circa 35-100, ''Institutio Oratoria'' 5.9.9-10), which regarded the sign as an instrument of inference. In his commentary on Aristotle’s ''De Interpretatione'', Ammonius said, "according to the division of the philosopher Theophrastus, the relation of speech is twofold, first in regard to the audience, to which speech signifies something, and secondly in regard to the things about which the speaker intends to persuade the audience." If we match DDC with this division, the first part belongs to DDC Book IV and the second part to DDC Books I-III. Augustine, although influenced by these theories, advanced his own theological theory of signs, with whose help one can infer the mind of God from the events and words of Scripture.
Books II and III of DDC enumerate all kinds of signs and explain how to interpret them. Signs are divided into natural (''naturalia'') and conventional (''data''); the latter is divided into animal (''bestiae'') and human (''homines''); the latter is divided into non-words (''cetera'') and words (''verba''); the latter is divided into spoken words (''voces'') and written words (''litterae''); the latter is divided into unknown signs (''signa ignota'') and ambiguous signs (''signa ambigua''); both the former and the latter are divided respectively into particular signs (''signa propria'') and figurative signs (''signa translata''), among which the unknown figurative signs belong to the pagans.
In addition to exegetical knowledge (Quintilian, ''Institutio Oratoria'' 1.4.1-3 and 1.8.1-21) which follows the order of reading (''lectio''), textual criticism (''emendatio''), explanation (''enarratio''), and judgment (''iudicium''), one needs to know the original language (Hebrew and Greek) and broad background information on Scripture (DDC 2.9.14-2.40.60).
Augustine’s understanding of signs includes several hermeneutical presuppositions as important factors. First, the interpreter should proceed with humility, because only a humble person can grasp the truth of Scripture (DDC 2.41.62). Second, the interpreter must have a spirit of active inquiry and should not hesitate to learn and use pagan education for the purpose of leading to Christian learning, because all truth is God’s truth (DDC 2.40.60-2.42.63). Third, the heart of interpreter should be founded, rooted, and built up in love which is the final goal of the entire Scriptures (DDC 2.42.63).
The sign does not function as its own goal, but its purpose lies in its role as a signification (''res significans'', DDC 3.9.13). God gave signs as a means to reveal himself; Christians need to exercise hermeneutical principles in order to understand that divine revelation. Even if the Scriptural text is obscure, it has meaningful benefits. For the obscure text prevents us from falling into pride, triggers our intelligence (DDC 2.6.7), tempers our faith in the history of revelation (DDC 3.8.12), and refines our mind to be suitable to the holy mysteries (DDC 4.8.22). When interpreting signs, the literal meaning should first be sought, and then the figurative meaning (DDC 3.10.14-3.23.33). Augustine suggests the hermeneutical principle that the obscure Scriptural verse is interpreted with the help of plain and simple verses, which formed the doctrine of "scriptura scripturae interpres" (Scripture is the Interpreter of Scripture) in the Reformation Era. Moreover, he introduces the seven rules of Tyconius the Donatist to interpret the obscure meaning of the Bible, which demonstrates his understanding that all truth belongs to God (DDC 3.3.42-3.37.56). In order to apply Augustine's hermeneutics of the sign appropriately in modern times, every division of theology must be involved and interdisciplinary approaches must be taken.
