"Knowledge of languages is the doorway to wisdom."
"As regards authority I so proceed. Boetius says in the second prologue to his Arithmetic, 'If an inquirer lacks the four parts of mathematics, he has very little ability to discover truth.' And again, 'Without this theory no one can have a correct insight into truth.' And he says also, 'I warn the man who spurns these paths of knowledge that he cannot philosophize correctly.' And Again, 'It is clear that whosoever passes these by, has lost the knowledge of all learning.'"

"Reasoning draws a conclusion, but does not make the conclusion certain, unless the mind discovers it by the path of experience."
"There are four chief obstacles in grasping truth ... namely, submission to faulty and unworthy authority, influence of custom, popular prejudice, and the concealment of our own ignorance accompanied by an ostentatious display of our knowledge."
"Cease to be ruled by dogmas and authorities; look at the world!"
"It is easier for a man to burn down his own house than to get rid of his prejudices."
"The strongest arguments prove nothing so long as the conclusions are not verified by experience. Experimental science is the queen of sciences and the goal of all speculation."
