“It is generally argued that our experience of free will presents a compelling mystery: On the one hand, we can't make sense of it in scientific terms; on the other, we feel that we are the authors of our own thoughts and actions.”

Popular Lectures on Scientific Subjects (1881)
Context: Now it is a universal law of the perceptions obtained through the senses that we pay only so much attention to the sensations actually experienced as is sufficient for us to recognise external objects. In this respect we are very one-sided and inconsiderate partisans of practical utility; far more so indeed than we suspect. All sensations which have no direct reference to external objects, we are accustomed, as a matter of course, entirely to ignore, and we do not become aware of them till we make a scientific investigation of the action of the senses, or have our attention directed by illness to the phenomena of our own bodies. Thus we often find patients, when suffering under a slight inflammation of the eyes, become for the first time aware of those beads and fibres known as mouches volantes swimming about within the vitreous humour of the eye, and then they often hypochondriacally imagine all sorts of coming evils, because they fancy that these appearances are new, whereas they have generally existed all their lives.

1920s, Whose Country Is This? (1921)
Context: From its very beginning our country has been enriched by a complete blend of varied strains in the same ethnic family. We are, in some sense, an immigrant nation, molded in the fires of a common experience. That common experience is our history. And it is that common experience we must hand down to our children, even as the fundamental principles of Americanism, based on righteousness, were handed down to us, in perpetuity, by the founders of our government.
