Incoherence arguments are intended to demonstrate that some philosophical position should be rejected because it is fatally flawed. I review the kinds of fatal flaws targeted in incoherence arguments, and argue that such arguments are not conclusive against the position they target, but merely pose challenges that require greater imagination. Furthermore, I claim that apparently incoherent positions have an instrumental value in expanding the intellectual resources of philosophy.

Resumo: O artigo apresenta e discute quatro objeções que têm sido direcionadas ao socioconstrutivismo, enquanto concepção de ciência: i) sua impossibilidade teórica; ii) sua implausibilidade teórica; iii) sua irrelevância; iv) sua indesejabilidade. O artigo sustenta a inadequação das quatro objeções, sugere a importância do socioconstrutivismo, mas defende que essa posição não é nem a única nem a melhor, para nossa compreensão da ciência, porém, apenas mais uma, dentre tantas contribuições filosóficas para essa compreensão. ABSTRACT: This paper introduces and discusses four (...) objections that have been adressed to social constructivism as an approach regarding science: i) its theoretical impossibility; ii) its theoretical implausibility; iii) its irrelevance; iv) its undesirability. This paper advocates the unsuitability of the four objections, means the significance of social constructivism, but argues for that this philosophical stance is neither the only nor the best one for our understanding of the science, but instead just one of many philosophical contributions to this understanding.

In this thesis I develop an account of the nature of limits of thought in terms of Husserl's phenomenology. I do this by exploring in terms of Husserl's phenomenology various ways thought-limits are encountered. Chapter One employs Husserl's analyses of meaning and intentionality to clarify the limits of conception and of questioning that emerge in wonder at the existence of the world. Chapter Two undertakes a critique of Husserl's refutation of psychologism in logic in order to clarify limits encountered in (...) reflection on the possibility of knowledge and how Husserl's phenomenology proposes to overcome these limits. Chapter Three turns to Husserl's own encounter with intellectual limits in his phenomenology of time-consciousness. Here I show how some of the limits explored in the first two chapters re-emerge on a transcendental level and argue that time-consciousness marks the limit to Husserl's phenomenology in the sense that it frustrates cognitive desire. In this way the thesis shows how Husserl's phenomenology both clarifies and itself illustrates an ineliminable desire in reason to exceed its limits, even when these limits are recognized. (shrink)
