“Perfect as is the wing of a bird, it never could raise the bird up without resting on air. Facts are the air of a scientist. Without them you never can fly. Without them your "theories" are vain efforts.”

“Man is a bird without wings and a bird is a man without sorrow.”

“A man without ambition is like a bird without wings”

“Without love, we are birds with broken wings.”

“Like birds whose wings are broken, you live without direction!”

“A weight is on the air, for ev'ry breeze
Has, bird-like, folded up its wings for sleep.”

“Birds seen flying around, you never see them too long on the ground, You want to be one of them…”

“Eneke the bird was asked why he was always on the wing and he replied: "Men have learned to shoot without missing their mark and I have learned to fly without perching on a twig."”

“The function which the wing performs against the air when the air is motionless is the same as that of the air moved against the wings when these are without motion.”

“The bird of truth would not be able to fly if it weren't for the air of lies we breathe.”
