Page 37 - is a definite combination of heterogeneous changes, both simultaneous and successive, in correspondence with external coexistences and sequences.
Page 56 - No war, or battle's sound Was heard the world around ; The idle spear and shield were high up hung ; The hooked chariot stood Unstained with hostile blood ; The trumpet spake not to the armed throng ; And kings sat still with awful eye, As if they surely knew their sovran Lord was by.
Page 246 - As Heaven and Earth are fairer, fairer far Than Chaos and blank Darkness, though once chiefs; And as we show beyond that Heaven and Earth In form and shape compact and beautiful, In will, in action free, companionship, And thousand other signs of purer life; So on our heels a fresh perfection treads, A power more strong in beauty, born of us And fated to excel us, as we pass In glory that old Darkness: nor are we Thereby more conquer'd, than by us the rule Of shapeless Chaos.
Page 192 - Man is all symmetry, Full of proportions, one limb to another, And all to all the world besides: Each part may call the farthest, brother ; For head with foot hath private amity, And both with moons and tides.
Page 129 - The following proposition seems to me in a high degree probable — namely, that any animal whatever, endowed with well-marked social instincts, would inevitably acquire a moral sense or conscience as soon as its intellectual powers had become as well developed, or nearly as well developed as in man.
Page 99 - A mass of living protoplasm is simply a molecular machine of great complexity, the total results of the working of which, or its vital phenomena, depend on the one hand upon its construction, and on the other, upon the energy supplied to it; and to speak of 'vitality' as anything but the name of a series of operations is as if one should talk of the horologity of a clock, "f Professor J.
Page 130 - Thus at last man comes to feel, through acquired and perhaps inherited habit, that it is best for him to obey his more persistent impulses. The imperious word ought seems merely to imply the consciousness of the existence of a rule of conduct, however it may have originated.
Page 153 - ... and he gives the same reason upon which Agassiz insisted — for in such case there would be nothing to account for the unlikeness of different organisms. Millions of species of plants and animals, more or less contrasted in their structures, are all mainly built up of these complex atoms. But if the polarities of these atoms determined the forms of the organisms they composed, the occurrence of such endlessly varied forms would be inexplicable. Hence, what we may call the chemical units are...
Page 158 - If we simply substitute the term polarity, for the circuitous expression — the power which certain units have of arranging themselves into a special form, we may, without assuming anything more than is proved, use the term organic polarity or polarity of the organic units, to signify the proximate cause of the ability which organisms display of reproducing lost parts.
Page 104 - ... circumstances would reproduce the whole ; but if the upper and lower surfaces were to differ in texture from each other and from the central portion, then all three parts would have to throw off gemmules, which when aggregated by mutual affinity would form either buds or the sexual elements, and would ultimately be developed into a similar organism. Precisely the same view may be extended to one of the higher animals ; although in this case many thousand gemmules must be thrown off from the various...
