Context

“This conduct is soon found out, it always gives rise to distrust and never reaches greatness. There is a difference between an ardent and a brilliant mind, a fiery spirit travels further and faster, while a brilliant mind is sparkling, attractive, accurate. Gentleness of mind is an easy and accommodating manner which always pleases when not insipid. A mind full of details devotes itself to the management and regulation of the smallest particulars it meets with. This distinction is usually limited to little matters, yet it is not absolutely incompatible with greatness, and when these two qualities are united in the same mind they raise it infinitely above others.” source
