We don't know what energy is, any more than we know what information is, but as a now robust scientific concept we can describe it in precise mathematical terms, and as a commodity we can measure, market, regulate and tax it.

New-age woolly-hat Glastonbury mystics weary me, sometimes, but they talk about energy, the energy of a place, of a person. We all know what they mean, but at the same time it has to be said that this is not energy that is going to show up on an autometer. We’re not talking about energy in the conventional sense that physics talks about energy. To me, energy is information – I think you can make that bold a statement. The only lines of energy that link up disparate sites in London are lines of information, that have been drawn by an informed mind. The energy that we put forth is information we have taken in. We will see a work of art and it will give us inspiration, it will give us energy. It’s given us information that we can turn to our own use and put out as something else. That’s the kind of energy that we – and psychogeography – are talking about.

The definition of random in terms of a physical operation is notoriously without effect on the mathematical operations of statistical theory because so far as these mathematical operations are concerned random is purely and simply an undefined term. The formal and abstract mathematical theory has an independent and sometimes lonely existence of its own. But when an undefined mathematical term such as random is given a definite operational meaning in physical terms, it takes on empirical and practical significance. Every mathematical theorem involving this mathematically undefined concept can then be given the following predictive form: If you do so and so, then such and such will happen.

We have just seen that, apart from money-capital, circulating capital is only another name for commodity-capital. But to the extent that labour power circulates in the market,it is not capital, no form of commodity-capital. It is not capital at all; the labourer is not a capitalist, although he brings a commodity to market, namely his own skin.

One might think this means that imaginary numbers are just a mathematical game having nothing to do with the real world. From the viewpoint of positivist philosophy, however, one cannot determine what is real. All one can do is find which mathematical models describe the universe we live in. It turns out that a mathematical model involving imaginary time predicts not only effects we have already observed but also effects we have not been able to measure yet nevertheless believe in for other reasons. So what is real and what is imaginary? Is the distinction just in our minds?

I’m very much a free market capitalist, actually. I don’t agree with a kind of totalitarian, one government or sort of universal law. I think what will happen and what is happening now is, in the same way as… In the way that countries make themselves attractive to investors through different pieces of legislation they offer, whether it’s secrecy in the case of the Cayman Islands or Switzerland, I think the fact that some countries now are offering very robust publishing laws, it will be that as information is global, what you might see is that these big internet companies like Google or Facebook, that have their servers, will start to relocate those servers to countries where they have less interference. In a way, you’re creating a kind of free market of freedom of information law.
