The gifts given to us by God must not be relinquished to those who speak ill of them and who are moved by envy or ignorance.
Do not share your inventions with many; share them only with the few who understand and love the sciences.
To disclose too much of one's inventions and achievements is one and the same thing as to give up the fruit of one's ingenuity.
Many are ready, when listening to the inventor, to belittle and deny his achievements so that he will no longer be heard in honourable places, but after some months or a year, they use the inventor's words in speech or writing or design.
