Page 86 - I find it, — at such times I shall ever feel it impossible to avoid the sharpest pang of which my nature is susceptible. For whether it be due to my intelligence not being sufficiently advanced to meet the requirements of the age, or whether it be due to the memory of those sacred associations which to me, at least, were the sweetest that life has given, I cannot but feel that for me, and for others who think as I do, there is a dreadful truth in those words of Hamilton...
Page 9 - Homer ruled as his demesne; Yet did I never breathe its pure serene Till I heard Chapman speak out loud and bold: Then felt I like some watcher of the skies When a new planet swims into his ken; Or like stout Cortez when with eagle eyes He stared at the Pacific— and all his men Looked at each other with a wild surmise— Silent, upon a peak in Darien.
Page 256 - Yet they seldom lose oxen : the way in which they discover the loss of one, is not by the number of the herd being diminished, but by the absence of a face they know. When bartering is going on, each sheep must be paid for separately. Thus, suppose two sticks of tobacco to be the rate of exchange for one sheep, it would sorely puzzle a Damara to take two sheep and give him four sticks.
Page 299 - ... natural theologians have had to contend. The external world appears, in this respect, to be at variance with our moral sense ; and when the antagonism is brought home to the religious mind, it must ever be with a shock of terrified surprise. It has been newly brought home to us by the generalizations of Darwin ; and therefore, as I said at the beginning, the religious thought of our generation has been more than ever staggered by the question — Where is now thy God ? But I have...
Page 258 - Dinah,' my spaniel, equally embarrassed on the other ; she was overlooking half a dozen of her new-born puppies, which had been removed two or three times from her, and her anxiety was excessive, as she tried to find out if they were all present, or if any were still missing. She kept puzzling and running her eyes over them backwards and forwards, but could not satisfy herself. She evidently had a vague notion of counting, but the figure was too large for her brain. Taking the two as they stood,...

That the development of a new organism, out of the fusion of two such packets of gemmules, is due to a summation of all the •developments of some of the gemmules which these two packets contain. 5. That a large proportional number of the gemmules in each packet, however, fail to develop, and are then transmitted in a dormant state to future generations, in any of which they may be developed subsequently...
Page 254 - ... was an excellent observer, mentions a case in which a man was anxious to shoot a crow. "To deceive this suspicious bird, the plan was hit upon of sending two men to the watch-house, one of whom passed on, while the other remained ; but the crow counted and kept her distance. The next day three went, and again she perceived that only two retired.
Page 86 - I am not ashamed to confess that, with this virtual negation of God, the universe to me has lost its soul of loveliness ; and although from henceforth the precept to ' work while it is day ' will doubtless but gain an intensified force from the terribly intensified meaning of the words that 'the night Cometh when no man can work,' yet when at times I think, as think at times I must, of the appalling contrast between the hallowed glory of that creed which once was mine, and the lonely mystery of existence...
Page 263 - Darwinism appeared, and under the guise of a foe did the work of a friend. It has conferred upon philosophy and religion an inestimable benefit, by showing us that we must choose between two alternatives. Either God is everywhere present in Nature, or He is nowhere. He cannot be here and not there ; He cannot delegate His power to demigods called
Page 163 - Nettuno ammirar l' ombra d'Argo. Così la mente mia tutta sospesa Mirava fissa immobile ed attenta, E sempre di mirar faeeasi accesa. A quella luce cotal si diventa, Che volgersi da lei per altro aspetto È impossibil che mai si consenta...
