Strana 237 - To noble raptures ; while my voice proclaims How exquisitely the individual Mind (And the progressive powers perhaps no less Of the whole species) to the external World Is fitted : — and how exquisitely, too — Theme this but little heard of among men — The external World is fitted to the Mind ; And the creation (by no lower name Can it be called) which they with blended might Accomplish : — this is our high argument.
Strana 639 - Centauri, and the Cross ; while to the north it fades away pale and dim, and is in comparison hardly traceable.
Strana 116 - Erscheinungen für Gesetze gelten können, in einer Hand und mit dem Experiment, das sie nach jenen ausdachte, in der anderen, an die Natur gehen, zwar um von ihr belehrt zu werden, aber nicht in der Qualität eines Schülers, der sich alles vorsagen läßt, was der Lehrer will, sondern eines bestallten Richters, der die Zeugen nötigt, auf die Fragen zu antworten, die er ihnen vorlegt.
Strana 423 - A student of mine asked me today to give him a reason for a fact which I did not know was a fact — and do not yet. He says that if a figure be anyhow divided and the compartments differently coloured so that figures with any portion of common boundary line are differently coloured — four colours may be wanted, but no more.
Strana 231 - Ut tamen et poscas aliquid voveasque sacellis Exta et candiduli divina tomacula porci, Orandum est ut sit mens sana in corpore sano.
Strana 639 - The general aspect of the southern circumpolar region, including in that expression 60° or 70° of SPD, is in a high degree rich and magnificent, owing to the superior brilliancy and larger development of the Milky Way : which, from the constellation of Orion to that of Antinous, is...
Strana 433 - Are you sure that it is impossible to trisect the angle by Euclid? I have not to lament a single hour thrown away on the attempt, but fancy that it is rather a tact, a feeling, than a proof, which makes us think that the thing cannot be done. But would Gauss's inscription of the regular polygon of seventeen sides have seemed, a century ago, much less an impossible thing, by line and circle?
Strana 229 - Fill'd with book-wisdom, pictured thought, and love That on its own creations spends itself. All things he understands, and nothing does. Profusely eloquent in copious praise Of action, he will talk to you as one Whose wisdom lay in dealings and transactions ; Yet so much action as might tie his shoe Cannot his will command ; himself alone By his own wisdom not a jot the gainer. Of silence and the hundred thousand things 'Tis better not to mention, he will speak, And still most wisely. — But, behold...
Strana 297 - Quisquis es, o modo quem ex adverso dicere feci, Non ego, quum scribo, si forte quid aptius exit, (Quando haec rara avis est) si quid tamen aptius exit', Laudari metuam ; neque enim mihi cornea fibra est. Sed recti finemque extremumque esse recuso EUGE tuum et BELLE.
