An Introduction to Radical Constructivism

The gods have certainty, whereas to us as men conjecture [only is possible] – Alcmaeon 1 PRELIMINARY REMARKS Within the limits of one chapter, an unconventional way of thinking can certainly not be thoroughly justified, but it can, perhaps, be presented in its most characteristic features anchored here and there in single points. There is, of course, the danger of being misunderstood. In the case of constructiv-ism, there is the additional risk that it will be discarded at first sight because, like skepticism – with which it has a certain amount in common – it might seem too cool and critical, or simply incompatible with ordinary common sense. The proponents of an idea, as a rule, explain its non-acceptance differently than do the critics and opponents. Being myself much involved, it seems to me that the resistance met in the 18th century by Giambattista Vico, the first true constructivist, and by Silvio Ceccato and Jean Piaget in the more recent past, is not so much due to inconsistencies or gaps in their argumentation, as to the justifiable suspicion that constructivism intends to undermine too large a part of the traditional view of the world. Indeed, one need not enter very far into constructivist thought to realize that it inevitably leads to the contention that man – and man alone – is responsible for his thinking, his knowledge and, therefore, also for what he does. Today, when behaviorists are still intent on pushing all responsibility into the environment, and sociobiologists are trying to place much of it into genes, a doctrine may well seem uncomfortable if it suggests that we have no one but ourselves to thank for the world in which we appear to be living. That is precisely what constructiv-ism intends to say – but it says a good deal more. We build that world for the most part unawares, simply because we do not know how we do it. That ignorance is quite unnecessary. Radical con-structivism maintains – not unlike Kant in his Critique – that the operations by means of which we assemble our experiential world can be explored, and that an awareness of this operating (which Ceccato in Italian so nicely called consapevolezza operativa) 2 can help us do it differently and, perhaps , better. This introduction, I repeat, will be limited to the exposition of a few aspects. The first section deals with the relation …
