Introduction
My research areas are the logic of science and the philosophy of biology (especially of systematics). I also develop computational applications for philosophers. I received my PhD from the University of Buenos Aires in 2020, I have a research scholarship from CONICET, and a teaching position at the Department of Philosophy of the University of Buenos Aires. I am a member of the Grupo ANFIBIO, the Centro de Filosofía e Historia de la Ciencia and the BA-Logic Group, among other groups.

In this paper, we present a way to translate the metainferences of a mixed metainferential system into formulae of an extended-language system, called its associated σ-system. To do this, the σ-system will contain new operators (one for each satisfaction standard), called the σ operators, which represent the notions of "belonging to a (given) satis...

La memética constituye un enfoque sobre la evolución cultural que se ha encontrado en el foco de la discusión y recolectado críticas de diverso tipo en las últimas décadas. El propósito de nuestro trabajo consiste en indagar si, más allá de las críticas y defensas existentes, puede considerarse que existe actualmente algún programa de investigación...

In this article, we provide three generators of propositional formulae for arbitrary languages, which uniformly sample three different formulae spaces. They take the same three parameters as input, namely, a desired depth, a set of atomics and a set of logical constants (with specified arities). The first generator returns formulae of exactly the g...

A given explanatory theory T falls into circular reasoning if the only way to determine its explanandum is through the application of T. To find an (often previous) underlying theory T ′ that determines T ′ s explanandum helps us save T from this accusation of circularity. We follow the structuralist view of theories in presenting and dealing with...

Resumen En el presente trabajo se analiza la controversia existente en el marco de la sistemática biológica en torno al estatus de la cladística. La utilización del método de parsimonia para la reconstrucción filogenética ha sido defendida apelando a un principio metodológico de simplicidad, así como a principios fácticos externos a la propia siste...
Chapter
The systemic approach to function proposes to ground every use of functional language in biology in a systemic analysis. A systemic analysis is a kind of explanation or procedure that parts from a capacity of a system and shows how this capacity is exercised by the system by decomposing it into other sub-capacities that are implemented in the (part...

In this article, I examine the issue of the alleged circularity in the determination of homologies within cladistic analysis. More specifically, I focus on the claims made by the proponents of the dynamic homology approach, regarding the distinction (sometimes made in the literature) between primary and secondary homology. This distinction is somet...

In a recent book, McShea and Brandon argue that the observed diversity and complexity of life are explainable by a principle they call the “zero-force evolutionary law” or “ZFEL”. Although this principle would be implicit in many explanations given by biologists, it would have never been made explicit. Assuming that this idea is interesting, and th...
Article
In this article, I develop three conceptual innovations within the area of formal metatheory, and present a computer program, called Reconstructor, that implements those developments. The first development consists in a methodology for testing formal reconstructions of scientific theories, which involves checking both whether translations of paradi...
Article
This article elaborates on McShea and Brandon’s idea that drift is unlike the rest of the evolutionary factors because it is constitutive rather than imposed on the evolutionary process. I show that the way they spelled out this idea renders it inadequate and is the reason why it received some (good) objections. I propose a different way in which t...

The propensity account of fitness intends to solve the classical tautologicity issue by identifying fitness with a disposition, the ability to survive and reproduce. As proponents recognized early on, this account requires operational independence from actual reproductive success to avoid circularity and vacuousness charges. They suggested that ope...

Due to an unfortunate turn of events, the family name of the first author was erroneously published as 'RoffÕ' in the original publication (PDF). The correct representation of the first author's family name is listed above and below.

In this article, we defend that incorporating a rejection operator into a paraconsistent language involves fully specifying its inferential characteristics within the logic. To do this, we examine a recent proposal by Berto (2014) for a paraconsistent rejection, which — according to him — avoids paradox, even when introduced into a language that co...
Article
An interesting metatheoretical controversy took place during the 1980’s and 1990’s between pattern and phylogenetic cladists. What was always at stake in the discussion was not how work in systematics should be carried out, but rather how this practice should be metatheoretically interpreted. In this article, we criticize Pearson’s account of the m...

El objetivo de este trabajo consiste en analizar las relaciones entre los modelos de optimalidad y la selección natural. Defenderemos que esas relaciones pueden dividirse en dos tipos, en tanto hay dos tipos de explicaciones seleccionistas, que llamaremos "históricas" y "ahistóricas". Las explicaciones históricas revelan como una población dada adq...

The adequacy of Elliott Sober’s analogy between classical mechanics and evolutionary theory—according to which both theories explain via a zero-force law and a set of forces that alter the zero-force state—has been criticized from various points of view. I focus here on McShea and Brandon’s claim that drift shouldn’t be considered a force because i...

Es una opinión extendida que la teoría de la selección natural, tal como fue formulada originalmente por Darwin de manera “cualitativa”, ha sido reemplazada por una versión cuantitativa superior, brindada por la genética de poblaciones. En este artículo se discute contra esa tesis, sosteniendo en cambio que ambas teorías son complementarias, no suc...
