Smatterers in learning are the most opinionated.

People usually think according to their inclinations speak according to their learning and ingrained opinions but generally act according to custom.

That is what leadership is all about: staking your ground ahead of where opinion is and convincing people not simply following the popular opinion of the moment.

I believe that the will of the people is resolved by a strong leadership. Even in a democratic society events depend on a strong leadership with a strong power of persuasion and not on the opinion of the masses.

We live in a society obsessed with public opinion. But leadership has never been about popularity.

It is my deliberate opinion that the one essential requisite of human welfare in all ways is scientific knowledge of human nature.

Useless knowledge can be made directly contributory to a force of sound and disinterested public opinion.

There are in fact two things science and opinion the former begets knowledge the later ignorance.

Science is the father of knowledge but opinion breeds ignorance.

The recipe for perpetual ignorance is: Be satisfied with your opinions and content with your knowledge.
