"it must be remembered that abduction, although it is very little hampered by logical rules, nevertheless is logical inference, asserting its conclusion only problematically or conjecturally, it is true, but nevertheless having a perfectly definite logical form. (...) only in deduction that there is no difference between a valid argument and a strong one. (...) an argument is none the less logical for being weak, provided it does not pretend to a strength that it does not possess (peirce, 1903, p.192).
"la abducción es una inferencia lógica que asevera su conclusión sólo problemática o conjeturalmente, es verdad, pero que no obstante, tiene una forma lógica perfectamente definida (…) sólo en la deducción donde no hay diferencia entre un argumento válido y un argumento fuerte (…) un argumento no deja de ser lógico por ser débil, con tal de que no aspire a una fuerza que no posee" (peirce 1903, p.192).
