Abstract

Roger Bacon was a very important logician in the thirteenth century and he had a profound influence on the development of logic, particularly in Oxford. He developed a theory of signs that had a lasting influence on the medieval and early modern philosophical tradition. The selection here presents his theory as developed in the beginning of On Signs.

Text excerpted from: Maloney, T.S. trans., 2013. On Signs. Toronto: Pontifical Institute of Mediaeval Studies, pp. 35-51, 56-62.

Notes

  1. 1.

    The term “species” as used in this work can mean either the division of a genus, e.g., man with respect to animal, or (as here) the mental representation of things outside the mind, such as images and concepts.…

  2. 2.

    See (1973) Boethius, Contra Eutychen et Nestorum I, ed. and trans. H.F. Stewart, E.K. Rand, revised by S.J. Tester, in Boethius: The Theological Tractates (London and Cambridge).

  3. 3.

    The Latin word for egg is “ovum” and it is spelled the same when used as the subject of a sentence or when it is the direct object of a verb. The Latin for horn is “cornu” and it is spelled the same in all grammatical cases.
