The most ignorant are the most conceited. Unless a man knows that there is something more to be known, his inference is, of course, that he knows every thing. Such a man always usurps the throne of universal knowledge, and assumes the right of deciding all possible questions. We all know that a conceited dunce will decide questions extemporaneous which would puzzle a college of philosophers, or a bench of judges. Ignorant and shallow-minded men do not see far enough to see the difficulty. But let a man know that there are things to be known, of which he is ignorant, and it is so much carved out of his domain of universal knowledge. And for all purposes of individual character, as well as of social usefulness, it is quite as important for a man to know the extent of his own ignorance as it is to know any thing else. To know how much there is that we do not know, is one of the most valuable parts of our attainments; for such knowledge becomes both a lesson of humility and a stimulus to exertion.

Genius, in truth, means little more than the faculty of perceiving in an unhabitual way.

Learning is borrowed knowledge; genius is knowledge innate.

So I'm not such a great believer in talent. Maybe I'd rather use the word ... because... I find that the people talk too much about the genius, and... correspondingly to the... in music and... mathematics... That's a dangerous word, and I'm not sure that it's socially beneficial to talk about... whether it exists or not. ...Maybe scientifically you can talk about the concept of genius, but it... does more damage sociologically, than it does good.

What's the point of having great knowledge and keeping them all to yourself?

Genius is seldom recognized for what it is: a great capacity for hard work.

Conceit spoils the finest genius. There is not much danger that real talent or goodness will be overlooked long; even if it is, the consciousness of possessing and using it well should satisfy one, and the great charm of all power is modesty.

The difference between genius and stupidity is: genius has its limits.

Conceal your learning from the company

Never display your learning, but on particular occasions. Reserve it for learned men, and let even these rather extort it from you, than appear forward to display it. Hence you will be deemed modest, and reputed to possess more knowledge than you really have. Never seem wiser or more learned than your company. The man who affects to display his learning, will be frequently questioned; and if found superficial, will be ridiculed and despised; if otherwise, he will be deemed a pedant. Nothing can lessen real merit (which will always shew itself) in the opinion of the world, but an ostentatious display by its possessor.

Whoever hasn’t yet arrived at the clear realization that there might be a greatness existing entirely outside his own sphere and for which he might have absolutely no feeling; whoever hasn’t at least felt obscure intimations concerning the approximate location of this greatness in the geography of the human spirit: that person either has no genius in his own sphere, or else he hasn’t been educated to the level of the classic.

Real knowledge is to know the extent of one’s ignorance. — Confucius The highest form of ignorance is when you reject something you don’t know anything about. — Wayne Dyer

Intellectual knowledge is ordinary, limited to the human faculties. It deals with the finite objects of the world of the creation of God; it is not concerned with the Creator. Gnosis (Marifat) is higher knowledge and directly deals with the Creator and the Divine Attributes. It is a gift of God.

A person who knows but a little will put on an air of knowledge. This is a matter of inexperience. When someone knows something well, it will not be seen in his manner.
