Life and writing

The checked catalogue gives Charles Darwin’s lifetime as 1809–1882 and credits Sue Asscher and David Widger for this electronic text. The book is written in English, and the linked text includes a preface to the second edition. The catalogue HTML ISBN identifies this digital reading. It is a historical scientific work, containing obsolete classifications and racial hierarchies; its catalogue description is not evidence that all its claims represent current science.

In the Introduction, Darwin answers those who assert confidently that science cannot solve the question of human origins. His contrast between ignorance and knowledge addresses that particular claim of impossibility. In Chapter XXI, he acknowledges that some of his own views may be erroneous, then distinguishes persistent false facts from views that can be refuted. The selected second extract stops within a longer source sentence, whose continuation describes correction opening a path toward truth. These passages invite scrutiny of evidence; they do not prove that all confidence is ignorance or that false hypotheses never cause harm.

I am much engaged, an old man and out of health, and I cannot spare time to answer your questions fully,—nor indeed can they be answered. Science has nothing to do with Christ, except in so far as the habit of scientific research makes a man cautious in admitting evidence. For myself, I do not believe that there ever has been any Revelation. As for a future life every man must judge for himself between conflicting vague probabilities. Wishing you happiness, I remain, &c.

I have said that in one respect my mind has changed during the last twenty or thirty years. Up to the age of thirty, or beyond it, poetry of many kinds, such as the works of Milton, Gray, Byron, Wordsworth, Coleridge, and Shelley, gave me great pleasure, and even as a school-boy I took intense delight in Shakespeare, especially in the historical plays. I have also said that formerly pictures gave me considerable, and music very great delight. But now for many years I cannot endure to read a line of poetry: I have tried lately to read Shakespeare and found it so intolerably dull that it nauseates me. I have also almost lost my taste for pictures or music.... My mind seems to have become a kind of machine for grinding general laws out of large collections of facts, but why this should have caused the atrophy of that (aesthetic) part of the brain alone, on which the higher tastes depend, I cannot conceive.... The loss of these tastes is a loss of happiness, and may possibly be injurious to the intellect, and more probably to the moral character, by enfeebling the emotional part of our nature.

Thus, from the war of nature, from famine and death, the most exalted object which we are capable of conceiving, namely, the production of the higher animals, directly follows. There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.

The following proposition seems to me in a high degree probable—namely, that any animal whatever, endowed with well-marked social instincts, the parental and filial affections being here included, would inevitably acquire a moral sense or conscience, as soon as its intellectual powers had become as well, or nearly as well developed, as in man. For, firstly, the social instincts lead an animal to take pleasure in the society of its fellows, to feel a certain amount of sympathy with them, and to perform various services for them.

To suppose that the eye with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been formed by natural selection, seems, I confess, absurd in the highest degree...The difficulty of believing that a perfect and complex eye could be formed by natural selection , though insuperable by our imagination, should not be considered subversive of the theory.
