Portrait of William Henry Hudson William Henry Hudson,  Green Mansions (1904)

“ But more than form and colour and that enchanting variability was the look of intelligence, which at the same time seemed complementary to and one with the all-seeing, all-hearing alertness appearing in her face; the alertness one remarks in a wild creature, even when in repose and fearing nothing; but seldom in man, never perhaps in intellectual or studious man. ”

Portrait of Leo Tolstoy Leo Tolstoy,  Anna Karenina (1877)

“ She showed that alertness, that swiftness of reflection which comes out in men before a battle, in conflict, in the dangerous and decisive moments of life—those moments when a man shows once and for all his value, and that all his past has not been wasted but has been a preparation for these moments. ”
