VALLEJO, Mauro. Paradoxes and successes of an imposible attempt: Analysis of Prosper Lucas' Traité philosophique et physiologique de l'hérédité naturelle (1847-1850). Anu. investig. [online]. 2009, vol.16, pp.207-215. ISSN 1851-1686.

This work analyses Prosper Lucas' Traité philosophique et physiologique de l'hérédité naturelle (1847-1850). First, we point out the historic value of that text, describing the way in which it continued its predecessors, and what influence it had over many authors of the 19th century. Second, we try to demostrate that several social problems were the sources of Lucas' text. On the other hand, we suggest that the notion of heredity coined by that author was equivocal, and we list the discursive strategies used in his theory. To conclude, this work try to evaluate whether Lucas' text is determinist or not, by analysing his notion of innatism.
