The article’s main aim is to analyse the sources of the opposition between the notions of abstraction and the concrete, widespread in common thinking, and the assumption that each abstraction is secondary to empirical (concrete) reality. The authors call these concepts “abstraction from the concrete”. The article consists of a historical introduction pointing to the potential sources of the above prejudice and a critical reconstruction of the pattern of thinking regarding the ladder of abstraction metaphor, based on the example of the work of Richard Swedberg. In its final section, The last part of the paper focuses on interpretation and analysis of the consequences of the author’s main argument and the definition of abstraction he proposes in light of Alfred Korzybski’s general semantics and Alfred N. Whitehead’s philosophy of science.

The aim of this paper is to present Peirce’s semiotics as an important factor in the genesis of Alfred North Whitehead’s doctrine of symbolism. I argue that Peirce had a direct impact on Whitehead’s earliest reflections on symbolism generally and mathematical symbolism particularly. From his first encounter with Charles Sanders Peirce’s semiotic doctrine, contrasted to that of George F. Stout, Whitehead derived a general doctrine of signs which he never abandoned and which formed the basis of his mature doctrine of symbolism. While in the first years of his Harvard professorship, Whitehead suffered a second, indirect, influence from Peirce, through the American philosophers he interacted with. His mature philosophy of perception is both the development and application of the doctrine derived from Peirce and Stout thirty years before, and a reply to the realist doctrines which stressed the symbolic nature of perceptual knowledge, most importantly Santayana’s. Whitehead’s own brand of realism rests on the assumption of a pansemiotic principle, obscurely and mediately derived from Peirce.

In this article Whitehead’s philosophy of mathematics is characterized as a Structural Second-Order Platonism and it is demonstrated that the Whiteheadian ontology is consistent with modern formal approaches to the foundation of mathematics. We follow the pathway taken by model-theoretically and semantically oriented philosophers. Consequently, it is supposed that all mathematical theories (understood as deductively closed set of sentences) determine their own models. These models exist mind-independently in the realm of eternal objects. From the metatheoretical point of view the hypothesis (posed by Józef Życiński) of the Rationality Field is explored. It is indicated that relationships between different models can be described in the language of modal logics and can further be axiomatized in the framework of the Second Order Set Theory. In conclusion, it is asserted that if any model (of a mathematical theory) is understood, in agreement with Whitehead’s philosophy, as a collection of eternal objects, which can be simultaneously realized in a single actual occasion, then our external world is governed by the hidden pattern encoded in the field of pure potentialities which constitute the above mentioned Field of Rationality. Therefore, this work can be regarded as the first step towards building a Logic of Rationality.
