Comet 12P Between Rosette and Cone Nebulas
Sandro Botticelli, Dante and Beatrice, n.d., The University of Texas, Austin
Light I beheld which as a river flowed,
Fulgid with splendour; and on either shore
The colours of a wondrous springtime showed.
And from the stream arose a glittering store
Of living sparks which, winging mid the blooms,
To rubies set in gold resemblance bore.
Dante, The Divine Comedy, Paradise, Canto XXX
‘Since fire is the rapid acquisition of oxygen, and since oxygen is a key indicator of life, fire on any planet would be an indicator of life on that planet.’
To consider this statement dialectically, one would think creatively – of the relationship between destruction and creation. Hegel did this from the idealist perspective –
‘Everything that surrounds us may be viewed as an instance of Dialectic. We are aware that everything finite, instead of being stable and ultimate, is rather changeable and transient; and this is exactly what we mean by that Dialectic of the finite, by which the finite, as implicitly other than what it is, is forced beyond its own immediate or natural being to turn suddenly into its opposite. We have before this (§80) identified Understanding with what is implied in the popular idea of the goodness of God; we may now remark of Dialectic, in the same objective signification, that its principle answers to the idea of his power. All things, we say – that is, the finite world as such – are doomed; and in saying so, we have a vision of Dialectic as the universal and irresistible power before which nothing can stay, however secure and stable it may deem itself.’

There is nothing in the world but matter in motion, and matter in motion cannot move otherwise than in space and time. Human conceptions of space and time are relative, but these relative conceptions go to compound absolute truth. These relative conceptions, in their development, move towards absolute truth and approach nearer and nearer to it. The mutability of human conceptions of space and time no more refutes the objective reality of space and time than the mutability of scientific knowledge of the structure and forms of matter in motion refutes the objective reality of the external world.

The Extraordinary Spiral in LL Pegasi
‘Human knowledge is not (or does not follow) a straight line, but a curve, which endlessly approximates a series of circles, a spiral. Any fragment, segment, section of this curve can be transformed (transformed one-sidedly) into an independent, complete, straight line, which then (if one does not see the wood for the trees) leads into the quagmire, into clerical obscurantism (where it is anchored by the class interests of the ruling classes).’

‘Spiral in Development: a figurative description of the process of development employed by Engels and Lenin in elucidating the law of the negation of the negation. Development produces in phenomena an apparent return to the old in the course of change: some features of a lower level are repeated at a higher level. This may be depicted graphically as a spiral in which each new coil repeats the preceding one, but at a higher level. Development in a spiral forms a contrast to the typically metaphysical idea of development as being motion along a closed circle without any new elements.’

As with their post (twice) on Hypatia the mystic and Neoplatonist, it is again to NASA’s credit that they put the above video on their website (also for a second time). I recommend the text below the video on that page, particularly the link ‘no one can know the future’ which leads to the abstract for the article ‘Searching the Internet for evidence of time travellers’.
No science website of the Australian government would dare to display, discuss and encourage such expressions of eagerness for intellectual creativity and the future. In Australia we march forward facing backwards, gagging on our ‘laid-back’, authoritarian, consumerist ‘decency’.
I post this on the day there has been yet another round of navel-gazing and spin in the media about why education in Australia continues to fall behind that in other developed nations.

‘Let art be content with its lofty, splendid mission of being a substitute for reality in case of its absence, and of being a textbook of life for man. Reality stands higher than dreams, and essential purpose stands higher than fantastic claims.’
