Page 107 - Here is a kind of attraction which in the mental world will be found to have as extraordinary effects as in the natural, and to show itself in as many and as various forms.
Page 193 - Newton, with some others of that strain, it is ambition enough to be employed as an underlabourer in clearing the ground a little, and removing some of the rubbish that lies in the way to knowledge...
Page 116 - ... conjunction, and have not, in any single instance, occurred separately either in experience or in thought, there is produced between them what has been called Inseparable, or less correctly, Indissoluble Association : by which is not meant that the association must inevitably last to the end of life — that no subsequent experience or process of thought can possibly avail to dissolve it ; but only that as long as no such experience or process of thought has taken place, the association is irresistible...
Page 375 - ... (I. p. 249.) Therefore, if we analyse the proposition that all mental phenomena are the effects or products of material phenomena, all that it means amounts to this: that whenever those states of consciousness which we call sensation, or emotion, or thought, come into existence, complete investigation will show good reason for the belief that they are preceded by those other phenomena of consciousness to which we give the names of matter and motion. All material changes appear, in the...
Page 148 - but a small and not even the most important part" of the whole extent of logical arguments. The universal principle (of "Substitution") suggested is in these words: "So far as there exists sameness, identity or likeness, what is true of one thing will be true of the other."

Page 150 - B allows us indifferently to place A where B was or B where A was, and there is no limit to the variety of special meanings which we can bestow upon the signs used in this formula consistently with its truth. Thus if we first specify only the meaning of the sign...
Page 374 - impressions of reflection" are excluded from among the primary elements of consciousness, nothing is left but the impressions afforded by the five senses, with pleasure and pain. Putting aside the muscular sense, which had not come into view in Hume's time, the questions arise whether these are all the simple undecomposable materials of thought ? or whether others exist of which Hume takes no cognizance ? Kant answered the latter question in the affirmative, in the " Kritik der reinen Vernunft...
Page 208 - ... organic beings which have ever lived on this earth may be descended from some one primordial form. But this inference is chiefly grounded on analogy and it is immaterial whether or not it be accepted. No doubt it is possible, as Mr. GH Lewes has urged, that at the first commencement of life many different forms were evolved; but if so we may conclude that only a very few have left modified descendants.
