Talking about viewing the Ocean "If I take the attitude of appreciation, it would be absurd to say that this wave is composed of chemical elements which I do not see; and if I take the attitude of physical explanation, it would be equally absurd to deny that such elements are all of which the wave is made. From the one standpoint, the ocean is really excited; from the other standpoint, the molecules are moving according to the laws of hydrodynamics. If I want to understand the meaning of this scene every reminiscence of physics will lead me astray; if I want to calculate the movement of my boat, physics alone can help me".(from the Introduction)
