The snow is on the ground, and still my people wait; They ask but their just dues, ere yet it be too late; For we are poor, our huts are cold, we starve, we die, While you are rich, your fires are warm, your harvests lie High heaped above the hunting grounds, our fathers' graves, We sold you long ago. Alas! our famished braves Have sold e'en their own graves! When dead, our bones shall stay To whiten on the ground, that our Great Father may More surely see where his Dacotah children died-- His dusky children whom ye robbed, and then belied. BUCKLE, DRAPER, AND A SCIENCE OF HISTORY _THIRD PAPER_ In any classification of our intellectual domain which it is possible to make on the basis of Principles now known to the Scientific world at large, the most fundamental characteristic should be, the distinctive separation of those departments of thought in which _Certainty_ is now attainable, from those in which only varying degrees of Probability exist, and the clear exhibition of that which is _positive and demonstrable knowledge_, in the strict sense of the term, as distinguished from that which is liable to be more or less fallible. Although the precise point at which, in some cases, the proofs of Probable Reasoning cease to be as convincing as those of Demonstration cannot be readily apprehended, yet the essential nature of the two _methods_ of proof is radically and inherently different, and is marked by the most distinctive results. In the latter case, we have always accuracy, precision, and certainty, _beyond the possibility of doubt_; in the former, always the conviction that, how strong soever the array of evidence may seem to be, in favor of a particular inference, there still remains a possibility that the conclusion may be modified or vitiated by the subsequent advancement of knowledge.
