The limits of Extinction Rebellion

Extinction Rebellion flags in Bristol July 2019

(reading time: 4 mins)

Why was I absent from Bristol’s Extinction Rebellion protests last week? I’m a left leaning voter who accepts time is running out for climate change action. Last winter I spent eight days upgrading my loft insulation to reduce my gas consumption by about 10% – which is one of many actions I’ve taken to reduce my carbon output. So why did I cycle past the protest each day instead of joining in?

Although XR are doing an important job of keeping climate change in the news cycle, I believe there’s a limit to what XR’s protests will achieve.

When is a tax not a tax? When it’s a carbon dividend

Scientists and economists have long advocated carbon taxes as the most effective way to remove carbon from the world economy. The carbon dividend is one of the few ways to make carbon taxes politically acceptable.

But while taxing carbon may be vital, people rarely vote for new taxes. While left of centre Europeans like me want increased funding for public services, history shows it’s an uphill task selling voters the tax increases needed to pay for them. It’s too easy for voters and politicians to think short-term and let future generations pay, with the cost of inaction rising all the time.

However the strength of the carbon dividend may be its cross party appeal. In different forms, the carbon dividend has long been popular with environmentalists (it is UK Green party policy), but is also gaining traction with Republicans and Libertarians. Continue reading…

The Human Animal – a breed apart?

For the majority of western history the only mind considered worthy of examination was the human mind. This is in part because we lacked the tools to examine how other animals experienced the world. However western science also developed within a Judeo-Christian cultural heritage – religious traditions which taught that God has taken us, and only us, over that threshold of animal awareness into the realm of moral beings, because we were the only animals with souls.

Although science has largely overtaken religion as a way of explaining human existence, like religion it has historically emphasised differences between humans and other animals, rather than common ground. In recent years more detailed experiments into animal cognition show much of what has been regarded as solely human characteristics, such as the potential for language, ability for abstract thought, the capacity for emotions, jealousy and cruelty even, can be found in other species to some extent. Here I want to consider some of that evidence with some observations on how this might be interpreted.

Taking a philosophical approach to scientific research might be seen as anthropomorphizing other species. Continue reading…

Free will, Determinism and Frogger

Is free will an illusion? Some recent neurological experiments have hit the headlines with that conclusion. The studies reveal that the conscious mind is sometimes slow to recognize a course of action the subconscious has already set in motion. Absence of free will is a possible explanation. Certainly most people don’t realise how much they invent reality to suit the events. Memory is highly subjective, and most of us occasionally use reason to justify decisions which are primarily motivated by our emotions.

Understandably scientists feel religion has got it wrong and science has got it right (generally true). Do some scientists further have a desire to liberate us from the burden of free will, apparently the remnant of an outdated belief system? Perhaps. Whether or not there is such a mission, there are significant problems with the assumptions behind these experiments, which mean going from free will may be an illusion to this proves free will is an illusion or even probably an illusion is quite a stretch.

You cannot be serious!

The cognitive studies involve simple motor tasks. For example, with brain activity being monitored, the subject presses a button Continue reading…
