Objectivist illusionism

I have come across a few enthusiasts for Ayn Rand lately and got involved in discussions with them. They would be of no importance but for the fact that her ideas have taken a firm hold on the political right. Supporters of Rand's philosophy might be found amongst the young people at Conservative Central Office who are responsible for developing party policies.

Rand invented a philosophy she called "objectivism". It has a set of fallacies at the heart of it, the principal one being that there is an objective reality which the human mind can apprehend through reason. There is, it is true, an objective reality and objective truth, but the human mind is unable to apprehend it.

It is true also that human beings have direct contact with reality through sense perception. The senses can, however, play nasty tricks on us at times - optical illusions are a good example. The meanings that are given to the raw data that the senses present to the mind are dependent on the state of mind of the individual observer. It will be so coloured by moods, emotions, theories, opinions, beliefs, levels of attention and the physical condition of the observer as to be anything but objective. We know this from reflection on our own personal experience. Recent understandings in neuroscience support this view.

This fuzziness is unavoidable and we deceive ourselves if we imagine that we are, or can be, objective.

If human knowledge is anything but objective, what of value can come from objectivism?

The dreadfulness of British governance

I wrote to my MP on two entirely separate issues recently. The first was to do with the replacement for the Inter City 125 train, which at £2.6 million per vehicle, is twice as expensive as it ought to be. The second concerned the benefits of a switch from business rate and Council Tax to a tax based on site values. In both cases, the replies were full of spurious, unsubstantiated assertions and completely flawed arguments. This is typical. You will not get an iota of sense from the government on any area of public policy at all - finance, economics, trade and employment, agriculture, housing, health, transport, energy. All junk. If you write to your MP you will invariably receive answers that are an insult to your intelligence, no matter what subject you are writing about. Of course they cannot understand statistics. They are innumerate. Whitehall is staffed with idiots with a high IQ. Look at their IT projects. And mind your purse, they will have that too.

How much more will the British tolerate?

The British are phlegmatic, tolerant and slow to rouse. Thus there was no great reaction after the terrorist attack in July 2005. The murder of Lee Rigby created a sense of outrage, but nothing more, since it appeared to be an isolated incident. Two serious incidents within a fortnight are another matter. Since the first major terrorist incident in 2001, authority has tried to persuade the public that Islam is a religion of peace, that these were isolated events, or the actions of deranged "lone wolves", having nothing to do with Islam, or to reassure that the chances of being killed in a terrorist attack were infinitesimally small. These assurances are are beginning to wear thin. They no longer convince. If government does not act effectively, people will take the law into their own hands. What, however, would effective action look like? What sort of effective action would not amount to rough justice for a lot of innocent people? Given the difficulties of keeping large n...

Battery trains fool’s gold

A piece by the railway news video Green Signals recently reported the fast charging trials for battery operated electric trains on the West Ealing to Greenford branch, in west London. In a comment under the video, I described the project as technological overkill, bearing in mind that before dieselisation in the 1960s it was worked by the tiny steam locomotives of the Great Western 1400 class, a 1932 design based on an 1870s design. The money that has been spent on the experiment would have paid for a small fleet of the old things. Elsewhere in the comments, I was critical of the 800 series trains. This produced a response from the makers of the video, as follows. “I may be grasping at straws here but I am guessing you don't like 8xx series trains all that much and rather wish we still had Kings, Castles and (for the branches) 14xx's. Fair? ” My reply was as follows... Yes you are grasping at straws. The model for long distance stock is the class 180, which is a 23 metre veh...
