The Last Days of John Brown

Anti-Slavery and Reform Papers

Read at North Elba, July 4, 1860. John Brown's career for the last six weeks of his life was meteor-like, flashing through the darkness in which we live. I know of nothing so miraculous in our history. If any person, in a lecture or conversation at that time...

Principles of Selection anciently followed, and their Effects.

On the Origin of Species Variation under Domestication

Let us now briefly consider the steps by which domestic races have been produced, either from one or from several allied species. Some effect may be attributed to the direct and definite action of the external conditions of life, and some to habit; but he woul...

Breeds of the Domestic Pigeon, their Differences and Origin.

On the Origin of Species Variation under Domestication

Believing that it is always best to study some special group, I have, after deliberation, taken up domestic pigeons. I have kept every breed which I could purchase or obtain, and have been most kindly favoured with skins from several quarters of the world, mor...

Character of Domestic Varieties; difficulty of distinguishing between Varieties and Species; origin of Domestic Varieties from one or more Species.

On the Origin of Species Variation under Domestication

When we look to the hereditary varieties or races of our domestic animals and plants, and compare them with closely allied species, we generally perceive in each domestic race, as already remarked, less uniformity of character than in true species. Domestic ra...

Effects of Habit and the Use or Disuse of Parts; Correlated Variation; Inheritance.

On the Origin of Species Variation under Domestication

Changed habits produce an inherited effect as in the period of the flowering of plants when transported from one climate to another. With animals the increased use or disuse of parts has had a more marked influence; thus I find in the domestic duck that the bo...

Causes of Variability

On the Origin of Species Variation under Domestication

When we look to the individuals of the same variety or sub-variety of our older cultivated plants and animals, one of the first points which strikes us, is, that they generally differ much more from each other, than do the individuals of any one species or var...

Introduction

On the Origin of Species

When on board H.M.S. 'Beagle,' as naturalist, I was much struck with certain facts in the distribution of the inhabitants of South America, and in the geological relations of the present to the past inhabitants of that continent. These facts seemed to me to th...

Epigrams

On the Origin of Species

“But with regard to the material world, we can at least go so far as this—we can perceive that events are brought about not by insulated interpositions of Divine power, exerted in each particular case, but by the establishment of general laws.” WHEWELL: Bridg...

Anti-Slavery and Reform Papers

From "The Liberator," March 28, 1845. Concord, Mass., March 12, 1845. Mr. Editor:— We have now, for the third winter, had our spirits refreshed, and our faith in the destiny of the Commonwealth strengthened, by the presence and the eloquence of Wendell Phil...

Part IV: Of the sceptical and other systems of philosophy

A Treatise of Human Nature Book 1: Of the understanding

Section I. Of scepticism with regard to reason In all demonstrative sciences the rules are certain and infallible; but when we apply them, our fallible and uncertain faculties are very apt to depart from them, and fall into error. We must, therefore, in every...

Life without Principle

Anti-Slavery and Reform Papers

Atlantic Monthly, Boston, October, 1863. At a lyceum, not long since, I felt that the lecturer had chosen a theme too foreign to himself, and so failed to interest me as much as he might have done. He described things not in or near to his heart, but toward h...

Thomas Carlyle and His Works

Anti-Slavery and Reform Papers

Graham's Magazine, Philadelphia, March, 1847. Thomas Carlyle is a Scotchman, born about fifty years ago, "at Ecclefechan, Annandale," according to one authority. "His parents 'good farmer people,' his father an elder in the Secession church there, and a man o...

Herald of Freedom

Anti-Slavery and Reform Papers

From "The Dial," Boston, April, 1844. We had occasionally, for several years, met with a number of this spirited journal, edited, as abolitionists need not to be informed, by Nathaniel P. Rogers, once a counsellor at law in Plymouth, still farther up the Merr...

Paradise (To Be) Regained

Anti-Slavery and Reform Papers

"Democratic Review," New York, November, 1843. We learn that Mr. Etzler is a native of Germany, and originally published his book in Pennsylvania, ten or twelve years ago; and now a second English edition, from the original American one, is demanded by his re...

A Plea for Captain John Brown

Anti-Slavery and Reform Papers

Read to the citizens of Concord, Mass., Sunday Evening, October 30, 1859. I trust that you will pardon me for being here. I do not wish to force my thoughts upon you, but I feel forced myself. Little as I know of Captain Brown, I would fain do my part to corr...

Civil Disobedience

Anti-Slavery and Reform Papers

I heartily accept the motto,—"That government is best which governs least"; and I should like to see it acted up to more rapidly and systematically. Carried out, it finally amounts to this, which also I believe,—"That government is best which governs not at al...

Prayer

Anti-Slavery and Reform Papers

Not with fond shekels of the tested gold,Nor gems whose rates are either rich or poor,As fancy values them: but with true prayers,That shall be up at heaven, and enter thereEre sunrise; prayers from preserved souls,From fasting maids, whose minds are dedicat...

Slavery in Massachusetts

Anti-Slavery and Reform Papers

An Address, delivered at the Anti-Slavery Celebration at Framingham, July 4th, 1854. I lately attended a meeting of the citizens of Concord, expecting, as one among many, to speak on the subject of slavery in Massachusetts; but I was surprised and disappointe...

Unconscious Selection.

On the Origin of Species Variation under Domestication

At the present time, eminent breeders try by methodical selection, with a distinct object in view, to make a new strain or sub-breed, superior to anything of the kind in the country. But, for our purpose, a form of selection, which may be called unconscious, a...
