Leonardo Da Vinci would disagree. In a letter to his brother he answered him to the news of the birth of his nephew, that he had created himself a great distraction.
> This is sent merely to inform you that a short time ago I received a letter from you from which I learnt that you have had an heir, which circumstance I understand has afforded you a great deal of pleasure. Now in so far as I had judged you to be possessed of prudence I am now entirely convinced that I am as far removed from having an accurate judgment as you are from prudence; seeing that you have been congratulating yourself in having created a watchful enemy, who will strive with all his energies after liberty, which can only come into being at your death.
