SOME REMARKS ON R. CARNAP'S CONCEPT OF CONSTRUCTION IN AUFBAU AND E. HUSSERL'S CONCEPT OF CONSTITUTION

This paper turns to the concept of constitution and some to it more immediately related notions contained in R. Carnap's Aufbau and Husserl's works that might have had some influence there, in order to find similarities and differences between them. It hopefully will contribute to this assessment of the plausible hypothesis, recently raised in the literature, of an influence of the father of phenomenology not explicitly sufficiently credited in Aufbau. The argumentative strategy was to expose, firstly in a separate way, the relevant points in each strand and then to make the comparative examination. This first analysis took place by two general aspects, namely, to address, on the one hand, the very relation of constitution and what is a system of it and, given the implicated foundationalism attributed to such notion, the data which are at the base of system like this. Then I move on to examine the differences and similarities between such expositions. As result, similarities were observed in that the two of them imply a broader thesis of foundationalism; they propose, in this, to an encompassing system. In addition, they contend that the fact that there is a difference between a lower-level object and a higher-level object does not imply between them mereological composition or some necessary commonality of properties. However, there are also differences regarding the kind of relationship that the notions of constituting imply in each case. Distinctions were also found about the role of sensations in each system; but in that sense, there is, in both perspectives, also similarities concerning their status. The paper concludes with the notion that there must be husserlian influences in the Aufbau not sufficiently credited. However, it is unreasonable the diagnosis of extreme importance of Husserl's influence.
