"The scientific method is the only one that allows us to approach the truth."

"Posterity will one day laugh at the sublime foolishness of the modern materialistic philosophy."

"The future belongs to those who believe in the beauty of their dreams."

"We must not forget that science, like all human activities, has its limits."

"It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is most adaptable to change."
