This is not yet a scientific age.

Science is a process for learning about nature in which competing ideas about how the world works are measured against observations.

It is our responsibility as scientists, knowing the great progress which comes from a satisfactory philosophy of ignorance, the great progress which is the fruit of freedom of thought, to proclaim the value of this freedom; to teach how doubt is not to be feared but welcomed and discussed; and to demand this freedom as our duty to all coming generations.

It is our responsibility to leave the people of the future a free hand.

Outside of their particular area of expertise scientists are just as dumb as the next person.
