Abstract

The article aims to show that the criticism of the psychophysiological theory of cognition formulated by Roman Ingarden in the work U podstaw teorii poznania (‘The Groundwork of Epistemology’) is in some aspects still sound. The psychophysiological theory of cognition is the forerunner of modern naturalized epistemology. Thus the author of this article undertakes to show that Ingarden’s critique applies to this modern epistemology. The paper focuses on an issue that is discussed in both theories, i.e. the problem of causal generation of cognition. Moreover, it investigates two allegations that Ingarden has formulated. The first concerns the causal explanations of the possibility of knowledge, namely the objection of a vicious circle in theory. The second concerns the objection that causal theory is unable to provide essential epistemological concepts and criteria that are necessary for the analysis of cognition. The author supports the charge of the vicious circle and agrees with the purport of the second objection by showing that it can be interpreted as the claim that causal theory is incapable of solving the problem of causal underdetermination of cognition. These responses seem to hold irrespective of whether one adopts foundationalism or anti‑foundationalism in epistemology.

Abstract

In this paper, four full-scale concrete columns with high-strength spiral stirrups (HSSS) are constructed and tested under low-cycle repeated loading. The specimens consisted of two castin- place columns and two precast concrete columns encased by a partly square steel pipe and bolt bars.The structural analysis of the HSSS columns of precast concrete conducted here is novel, and past experimental data for this are not available.To assess the seismic behavior and failure mechanisms of the new connections, quasi-static tests were carried out on columns prefabricated with them and cast-in-place specimens.The responses of all columns were compared, and the results showed that the failure modes of all columns are the large eccentric damage, and the destruction of all specimens occur at the column foot. The anti-seismic property of the precast HSSS concrete columns was comparable to that of the HSSS cast-in-place columns. A comparison of such performance parameters as energy dissipation and coefficient of ductility revealed that the precast HSSS concrete columns are suitable for use in earthquake zones.
