Sin embargo, un estudio comparativo entre los principios de ambas ciencias, así como de los fundamentos de su constitución, arroja el resultado primario de que sólo es posible hablar de principios propiamente a priori en las matemáticas, manteniendo para los de la ciencia natural un estatus diferente. La elucidación de la naturaleza y modo de construcción de estos últimos mostrará que Immanuel Kant estaba caracterizando un proceder común en la ciencia del siglo XVIII y que aún hoy puede leerse en la práctica científica estándar.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract This paper considers the kantian statement that the natural science, the same as the mathematics, it contains synthetic a priori judgments as principles. However, a comparative study among the principles of both sciences, as well as of the foundations of their constitution, it throws the primary result that it is only possible to speak properly of a priori principles in the mathematics, maintaining for those of the natural science a different status. The explanation of the nature and way of construction of these last ones will show that Kant was characterizing a procedure common in the science of the XVIII century, and that today it can still be read in the standard scientific practice.]]></p></abstract>
