 The Car Example for OOP

The `Car extends Vehicle` or `Duck extends Bird` type of tutorial obscures more than it illuminates. In good OO programming, we don’t make class hierarchies in order to satisfy our inner Linnaeus. We make class hierarchies in order to simplify the code by allowing different parts of it to be changed independently of each other, and to eliminate duplication (which comes to the same thing). Without any context as to what the code needs to accomplish, you can’t make a judgment about whether...

 Metaphor in Science

Metaphor in science, Boyd suggests, is a version of the everyday process in which a metaphor is pressed into service to fill gaps in a language’s vocabulary, like rabbit ears to refer to the antennas that used to sprout from the tops of television sets. Scientists constantly discover new entities that lack an English name, so they often tap a metaphor to supply the needed label: selection in evolution, kettle pond in geology, linkage in genetics, and so on. But they aren’t shackled by the...

 The Universality of Analogy

This reversibility and this polyvalency endow analogy with a universal field of application. Through it, all the figures in the whole universe can be drawn together. There does exist, however, in this space, furrowed in every direction, one particularly privileged point: it is saturated with analogies (all analogies can find one of their necessary terms there), and as they pass through it, their relations may be inverted without losing any of their force. This point is man: he stands in propo...

I shall define a posthuman as a being that has at least one posthuman capacity. By a posthuman capacity, I mean a general central capacity greatly exceeding the maximum attainable by any current human being without recourse to new technological means. I will use general central capacity to refer to the following: healthspan – the capacity to remain fully healthy, active, and productive, both mentally and physically cognition – general intellectual capacities, such as memory, deductive an...

 The Similies

OF COURSE we were hardly all the similes the Ariekei spoke. Some were animal or inanimate: there was a house in Embassytown out of which, many years before, the Hosts had taken all the furniture, then put it back, to allow some figure of speech. The split stone, made so they could speak the thought, it’s like the stone that was split and put together again. Most, though, were Terre men and women: there was something in us that facilitated. Many similes, of course, were uninterested in thei...

The Ariekei can only speak in analogy, not lie, and not speculate. Because of this, they need people to serve as similies, references for their language.
