"Never stop acquiring the commonsense, it is as good as the knowledge."
"You don't need to climb a mountain to know that it's high."
"Collecting facts is important. Knowledge is important. But if you don't have an imagination to use the knowledge, civilization is nowhere."
"The ruin of a man's teaching comes of his followers, such as having never touched the foundation he has laid, build upon it wood, hay, and stubble, fit only to be burnt. Therefore, if only to avoid his worst foes, his admirers, a man should avoid system. The more correct a system the worse will it be misunderstood; its professed admirers will take both its errors and their misconceptions of its truths, and hold them forth as its essence."
"Every fiction has its base in fact."
"If I want to understand an individual human being, I must lay aside all scientific knowledge of the average man and discard all theories in order to adopt a completely new and unprejudiced attitude. I can only approach the task of understanding with a free and open mind, whereas knowledge of man, or insight into human character, presupposes all sorts of knowledge about mankind in general."

"Common sense steps in here and says: Separate the parts you want to be mobile from the parts you want to be inert. You have seen the result, and I know many have the skill to apply it."
"It becomes a giant's task to compute the result when the effect of cross seas, wind at all angles and ever varying force, arched surfaces, head resistance, ratio of weight to area, and the intelligence of the guiding power crop up."
"If you direct your attention to the position of a bird with regard to the wave surface, it will speedily be noticed to be nearly always on the rising side or face of the wave and moving apparently at right angles to the wave's course, but really diagonal to it."
"And from a poise at this station the plane may swoop down, at great disadvantage if close to the back of the wave, at various slopes and directions till it cuts into the air that is being raised by the face of the following wave, which again enables it to resume its velocity."
"The plane is simply abstracting the power stored in the wave by a distant gale, and using it to counteract gravity. And if the work be continued long enough, or a multitude of planes be continually drawing on the reservoir of power, the wave must inevitably be flattened."
"The wings are moved several times by hand to charge the crank chamber with mixture, which flows on through the external pipe and inlet valve to the compression space and cylinder."
"The most ordinary conditions for observing sailing birds are then the wind and sea are both aft."
"As to the effect of the wave on the air, we will suppose the water to be quite flat and the air motionless, a heavy undulation comes on the scene, it has to pass, so it pushes the air up with its face, letting it fall again as its back glides onwards."
"The closer the bird is to the surface of the water, the firmer and more inelastic is the uplift of the rising air. The bird appears to almost feel the surface with the tip of its weather wing."
