The greater part of the substance of the following Essays has already been published in the form of Oral Discourses, addressed to widely different audiences, during the past three years. Upon the subject of the second Essay, I delivered six Lectures to the Working Men in 1860, and two, to the members of the Philosophical Institution of Edinburgh in 1862.

Hypothesis Of Molecular Vortices. In thermodynamics as well as in other branches of molecular physics, the laws of phenomena have to a certain extent been anticipated, and their investigation facilitated, by the aid of hypotheses as to occult molecular structures and motions with which such phenomena are assumed to be connected. The hypothesis which has answered that purpose in the case of thermodynamics, is called that of "molecular vortices," or otherwise, the "centrifugal theory of elasticity. (On this subject, see the Edinburgh Philosophical Journal, 1849; Edinburgh Transactions, vol. xx.; and Philosophical Magazine, passim, especially for December, 1851, and November and December, 1855.)
William John Macquorn Rankine
"We have all been affected as composers, as teachers, as musicians by recordings to an extent that cannot possibly be calculated as yet or predicted for the future. The music which is being most widely disseminated and most widely discussed, and therefore most widely imitated and influential, is that music which is available on records. The music that is only published is very little known. I don't think one can possibly exaggerate the extent to which the climate of music today is determined by the fact that the total Webern is available on records, that the total Schoenberg is becoming available." Quoted in Classic Essays on Twentieth-Century Music, ISBN 0028645812.
Milton Babbitt
The reckoning with idealism as a view of life is universal, but it also touches on something central in art-its life’s substance. One must understand that it is impossible to distinguish between a picture’s form and its substance. As the flower’s structure is governed by the intentional tension (when it loses the sap the form is lost), so also with art the substance creates the tension. Form and substance are one and the same. Form is the life expression and substance the living painting.

Dr. Grant took me occasionally to the meetings of the Wernerian Society, where various papers on natural history were read, discussed, and afterwards published in the 'Transactions.' I heard Audubon deliver there some interesting discourses on the habits of N. American birds, sneering somewhat unjustly at Waterton. By the way, a negro lived in Edinburgh, who had travelled with Waterton, and gained his livelihood by stuffing birds, which he did excellently: he gave me lessons for payment, and I used often to sit with him, for he was a very pleasant and intelligent man.
Charles Darwin
It was necessary that the very noble form of man, which is the image and likeness of God... should be joined to the substance of dust and darkness, the source of all defect and loss. For these reasons the Creator gave to the form of man power, rule, and dominion over the substance;—the form can subdue the substance, refuse the fulfillment of its desires, and reduce them, as far as possible, to a just and proper measure.
