    Note di filosofia della scienza ad uso di genetisti

    No full text
    Lo strumento scientifico ha avuto uno sviluppo vertiginoso nel campo delle professioni legali, divenendo fattore sempre più determinante nell'ambito giudiziario, soprattutto in quello penale. È, infatti, ormai impossibile pensare a un processo che non contenga elementi d'indagine caratterizzati in modo scientifico - quali, ad esempio, le impronte digitali, le analisi balistiche, le analisi tossico-chimiche, le analisi relative a tracce o frammenti di sangue, le analisi genetiche -, o che prescinda dalla testimonianza di un esperto in un certo ambito scientifico. Questo volume si propone di introdurre alcuni concetti di genetica e di statistica, ma anche di filosofia della scienza, di cui dovrebbero essere a conoscenza tutte le parti impegnate in un processo, per affrontare il proprio lavoro con maggiore serenità, consapevolezza ed efficacia

    On molecular mechanisms and contexts of physical explanation

    No full text
    In this article, two issues regarding mechanisms are discussed. The first concerns the relationships between “mechanism description” and “mechanism explanation.” It is proposed that it is rather plausible to think of them as two distinct epistemic acts. The second deals with the different molecular biology explanatory contexts, and it is shown that some of them require physics and its law

    Beyond the Metaphor of Genetic Information

    The notion of ‘genetic information’ is extremely controversial. Though dominant in the biological jargon and decisive in the historical development of molecular biology, philosophical thinking typically dismisses it as a vacuous (or even dangerous) metaphor for science that should be abandoned. In this paper, we analyze this notion from the point of view of the philosophy of information. After briefly revising the history of the notion, we show that most of the current usages of ‘genetic information’ are actually metaphorical and theoretically untenable both at the cellular and phenotypic level. But instead of rejecting the notion as a mere metaphor, we propose a way to rescue ‘genetic information’ by considering it as a kind of environmental information, that is information composed by “natural data” arising from the correlation between two systems. Then we highlight the positive and negative features of our proposal. Finally, we suggest that it is only within the ethical discourse that the notion can be fully maintained
