List of "imperceptible" Human Motions
Humans, like all known things in the universe, are in constant motion, however, aside from obvious movements of the various external body parts and locomotion, humans are in motion in a variety of ways which are more difficult to perceive. Many of these "imperceptible motions" are only perceivable with the help of special tools and careful observation. The larger scales of "imperceptible motions" are difficult for humans to perceive for two reasons: 1) Newton's laws of motion (particularly Inertia) which prevent humans from feeling motions of a mass to which they are connected, and 2) the lack of an obvious frame of reference which would allow individuals to easily see that they are moving. The smaller scales of these motions are too small for humans to sense.

“Religious literature has eminent examples, and if we run over our private list of poets, critics, philanthropists and philosophers, we shall find them infected with this dropsy and elephantiasis, which we ought to have tapped.”
—Ralph Waldo Emerson (1803–1882)
“A man’s interest in a single bluebird is worth more than a complete but dry list of the fauna and flora of a town.”
—Henry David Thoreau (1817–1862)
“How like a prodigal doth nature seem,
When thou, for all thy gold, so common art!
Thou teachest me to deem
More sacredly of every human heart,
Since each reflects in joy its scanty gleam
Of Heaven, and could some wondrous secret show,
Did we but pay the love we owe,
And with a child’s undoubting wisdom look
On all these living pages of God’s book.”
—James Russell Lowell (1819–1891)
“Sometimes we sailed as gently and steadily as the clouds overhead, watching the receding shores and the motions of our sail; the play of its pulse so like our own lives, so thin and yet so full of life, so noiseless when it labored hardest, so noisy and impatient when least effective; now bending to some generous impulse of the breeze, and then fluttering and flapping with a kind of human suspense.”
—Henry David Thoreau (1817–1862)
