Doodles

The margins of all my lecture notes used to be full of doodles, usually faces. I wonder whether this is inherited – my mother often used to draw faces on random envelopes and other scraps of paper. You could tell if she had had a long chat on the phone, usually with my uncle, by the number of drawings she made. (Their chats tended to consist of him holding forth at length and her occasional ‘yes’, ‘of course’, ‘aha’, to let him know she was still there, sitting in the chilly hall where the phone lived. This was in the days when you answered the phone by reeling off the number: ‘Pontefract-two-double-five-four’.)

The same habit still resurfaces whenever I find myself at a meeting or something, listening, with a pen and a piece of paper to hand.

Save the NHS

Today there is a march happening in London in support of the National Health Service. To my shame, I am not there.

But to express my solidarity with the marchers, here’s a post I put on facebook the other day:

If the NHS is ‘unsustainable’ while a privatised version would be ‘sustainable’, what does that imply? That people are more willing to pay for their own care via private insurance than for everyone’s care via higher national insurance or taxes (and probably to pay more overall, as private systems have to generate profit as well as cover costs)? – or rather that the current privatising government is populated and backed by people who would be reaping those profits?
If we as a country really ‘can’t afford’ the NHS, we wouldn’t be able to afford a private healthcare system either, unless of course the hidden factor is that in the private system some people just get left out altogether. But that ignores the social and human costs of not treating people – costs which the NHS was designed to avoid.

What we make we can break – but why must we?

Only Connect – one for the nerds

There’s a quiz programme on the BBC which I like, called Only Connect, which used to allow viewers to submit puzzles to their website. For some reason, yesterday, I found myself constructing one of these puzzles. It turns out you can’t submit them to the Only Connect website anymore, so, in the spirit of waste-not-want-not, here it is.

The idea is that you sort the grid into four groups of four. In the words of Wikipedia: ‘Each team receives a wall of 16 clues and must figure out a perfect solution, consisting of four groups of four connected items. The puzzles are designed to suggest more connections than actually exist, and some clues appear to fit into more than one category.’ A word of warning, groups may involve an element of word play.

Let me know if you would like the answers 🙂

And here’s a re-use of a totally irrelevant drawing of one of my favourite Freud paintings – yes, I am trying to distract myself from politics…

Reasoning for kids (and others) – how to argue or how not to – or an introduction to the idea of logic

When learning and teaching logic as part of philosophy, I took it for granted as a course requirement, not really thinking very hard about its social, practical significance, much in the way you learned calculus in a maths course. But lately, for some reason, I’ve been thinking harder about that significance, which led me to draft a preliminary attempt at an intro to logic aimed young people (though I think I missed that target). Here’s a bit of it:

Sometimes people disagree – about what is true, about what is right, about what to do, about what they want or like.

Sometimes disagreement doesn’t matter much – we can agree to disagree without it causing a problem.

Sometimes disagreements do matter, because they affect important decisions or our understanding of the world.

If a disagreement must be settled, some ways of finding agreement are better than others.

Bad ways of arguing include:

  • Trying to ‘win’ regardless of truth/evidence
  • Force, shouting, use of power (bullying)
  • Manipulation of people’s emotions
  • Logical fallacies, or rhetorical tricks.

Good ways of arguing include:

  • Respecting alternative views and acknowledging errors
  • Seeking truth (in matters of fact)
  • Seeking compromise (in matters of opinion)
  • Looking for evidence
  • Arguing logically, soundly – i.e. using forms of reason that, when you start from truths, will reach more truths.

‘Argument’ often means a conflict between people, a dispute or a fight. But it also means a sequence of thoughts that lead to a conclusion. This kind of argument can be used to persuade people to agree about something or to do something. But arguments are not just for persuading people to agree with you. They are also for testing your own beliefs or arriving at new ones, or for working out what to do.

A valid argument is a sequence of thoughts or sentences that lead from a starting point, called assumptions or premises, to conclusions, so that if you know the premises are true you can be sure (or confident) that the conclusion is too. This kind of argument can help us solve problems, make decisions, find things out.

To emphasise, a chain of reasoning consists of statements that can be judged true or false – that is, it must involve complete sentences, not fragments of sentences, or isolated expressions of feeling. So it is important to understand what a sentence is and to construct arguments out of well-formed sentences. Engaging in genuine debate, not just ‘having a row’, involves composing and/or attending to statements which are well-formed, in this sense: they express a complete thought which can be assessed for its truth-value, which makes a specific claim about reality. An interrupted sentence cannot do this. Someone who tries to persuade an audience by stringing together incomplete sentences or buzzwords is not making a rational argument. At best they are creating an impression, a word cloud, which may induce a feeling in the audience or even encourage a belief, but they cannot justify the feeling or prove the belief without engaging with truth.
