On Frege's 'Modes of Presentation' in Signs

Gottlob Frege introduced a new dimension to the characterization of signs - that of 'mode of presentation'. The same referent may be represented by different signs and in different manners, revealing it with dissimilar depth and profundity. The mode of presentation varies due to the fact that the same denoted object changes in the course of time and under alternating circumstances, but also because people designating it have unequal means for doing so. Herein I undertake to explicate these facts as they occur in semiotic reality.
