A window on the world

NGC 3324 is also called the Gabriela Mistral nebula, because of the striking resemblance with the Nobel Prize winning Chilean poet, who was born and raised in the Elqui region, home to the Cerro Tololo, Cerro Pachon and Cerro Morado professional observatories.

A man that looks on glasse

On it may stay his eye,

Or if he pleaseth, through it passe

And then the heav’n espie

George Herbert

If the glass through which we look is the sensible world, then with ‘heav’n’ we have Platonism. Substitute ‘atoms and void’ and it is Democritean. If the word were ‘real’, it would fit either philosophy.

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.

Astronomy, formal and dialectical reason

fires_mccolgan_960

Formal reason:

‘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.’

Dialectical reason:

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.
