Faleceu o Francisco Miró Quesada Cantuarias:
Miró Quesada helped me. On the one hand, it should be recalled that, by that time, all logics
unavoidably condemned contradictions. The new logic in which I worked faced too much
resistance, it was badly divulged, and those that got to know it were in general sceptics. By
that time I wrote to Miró Quesada, who saw the new logic with great enthusiasm,
requesting a name for it. I remember as it was today that he answered with three proposals:
it could be called metaconsistent, ultraconsistent or paraconsistent. After commenting on
these possible denominations, he stated that, from his viewpoint, he preferred the latter. The
term paraconsistent sounded splendid and I began to use it, suggesting that people inter-
ested on this logic did the same. Two or three months later, the miracle took place; the term
spread through the world, all the centres directly or indirectly related to logic, from northern
to southern hemisphere, began to employ it. I believe that few times in the history of
science (definitely in the history of logic) something similar has happened, for not only the
word run the whole world, but the very logic called by Miró Quesada “paraconsistent”
received a formidable push. It became one of the most discussed theories of logic of our
time. (Newton da Costa, “La Filosofia de la Logica de Francisco Miró Quesada Cantuarias,” in
Logica, Razon y Humanismo, Lima, 1992, pp. 69–78.)
O Quesada teve muitas atuações, entre elas:
- ministro da educação do Peru
- embaixador do Peru na França
- presidente da FISP (Federação Internacional das Sociedades de Filosofia) que organiza a cada cinco ano o congresso mundial de filosofia
- propôs a expressão "lógica paraconsistente" ao Newton da Costa (ver em baixo)
etc:
A ultima vez que eu encontrei ele foi em 1995 no nono congresso brasileiro de filosofia em São Paulo

Several years ago, I needed a convenient and meaningful denomination for a logic that did
not eliminate contradictions from the outset as being false, i.e., as absolutely unacceptable.Miró Quesada helped me. On the one hand, it should be recalled that, by that time, all logics
