Man is arrogant in proportion to his ignorance. - Edward Bulwer-Lytton

The man who succeeds above his fellows is the one who, early in life, clearly discerns his object, and towards that object habitually directs his powers. Even genius itself is but fine observation strengthened by fixity of purpose. Every man who observes vigilantly and resolves steadfastly grows unconsciously into genius.

It is not Wisdom, but Ignorance, which teaches men presumption; Genius may be sometimes arrogant, but nothing is so diffident as Knowledge.

The mind profits by the wrecks of every passion, and we may measure our road to wisdom by the sorrows we have undergone.
