Mientras que el amor de un buen padre siente por sus hijos es tan puro que no desea obtener nada de ellos y no quiere poseerlos de otro modo que como… - René Descartes

Those who possess
the strongest reasoning and who best order their thoughts in order to
make them clear and intelligible can always best persuade others of what
they are proposing, even if they were to speak only Low Breton and had
never learned rhetoric.

Good sense is, of all things among men, the most equally distributed; for every one thinks himself so abundantly provided with it, that those even who are the most difficult to satisfy in everything else, do not usually desire a larger measure of this quality than they already possess.

[...] the diversity of our opinions, consequently, does not arise from some being endowed with a larger share of reason than others, but solely from this, that we conduct our thoughts along different ways, and do not fix our attention on the same objects. For to be possessed of a vigorous mind is not enough; the prime requisite is rightly to apply it. The greatest minds, as they are capable of the highest excellences, are open likewise to the greatest aberrations; and those who travel very slowly may yet make far greater progress, provided they keep always to the straight road, than those who, while they run, forsake it.
