"The Plot Against People," The New York Times (1968-06-18)
“The great break in the organic chain between man and his nearest allies, which cannot be bridged over by any extinct or living species, has often been advanced as a grave objection to the belief that man is descended from some lower form; but this objection will not appear of much weight to those who, convinced by general reasons, believe in the general principle of evolution. Breaks incessantly occur in all parts of the series, some being wide, sharp and defined, others less so in various degrees; as between the orang and its nearest allies—between the Tarsius and the other Lemuridæ—between the elephant and in a more striking manner between the Ornithorhynchus or Echidna, and other mammals. But all these breaks depend merely on the number of related forms which have become extinct. At some future period, not very distant as measured by centuries, the civilised races of man will almost certainly exterminate and replace throughout the world the savage races. At the same time the anthropomorphous apes, as Professor Schaaffhausen has remarked, will no doubt be exterminated. The break will then be rendered wider, for it will intervene between man in a more civilised state, as we may hope, than the Caucasian, and some ape as low as a baboon, instead of as at present between the negro or Australian and the gorilla.”

The sentence "At some future period … the savage races" is often quoted out of context to suggest that Darwin desired this outcome, whereas in fact Darwin simply held that it would occur.

Nobel lecture (1978)
Context: Not only has our generation lost faith in Providence but also in man himself, in his institutions and often in those who are nearest to him. In their despair a number of those who no longer have confidence in the leadership of our society look up to the writer, the master of words. They hope against hope that the man of talent and sensitivity can perhaps rescue civilization. Maybe there is a spark of the prophet in the artist after all.

McCulloch v. Maryland (1819)
Context: In America, the powers of sovereignty are divided between the Government of the Union and those of the States. They are each sovereign with respect to the objects committed to it, and neither sovereign with respect to the objects committed to the other. We cannot comprehend that train of reasoning, which would maintain that the extent of power granted by the people is to be ascertained not by the nature and terms of the grant, but by its date. Some State Constitutions were formed before, some since, that of the United States. We cannot believe that their relation to each other is in any degree dependent upon this circumstance. Their respective powers must, we think, be precisely the same as if they had been formed at the same time. Had they been formed at the same time, and had the people conferred on the General Government the power contained in the Constitution, and on the States the whole residuum of power, would it have been asserted that the Government of the Union was not sovereign, with respect to those objects which were intrusted to it, in relation to which its laws were declared to be supreme? If this could not have been asserted, we cannot well comprehend the process of reasoning which maintains that a power appertaining to sovereignty cannot be connected with that vast portion of it which is granted to the General Government, so far as it is calculated to subserve the legitimate objects of that Government.
