There was a big fight over Quantum Physics, in which Einstein defended Realism and Bohr defended Instrumentalism. That is a massive simplification, it seems, but it is an accepted-enough® simplification, so much so that this pseudo-quote is assigned to Bohr by PBS Space Time:

“It is meaningless to assign reality to the universe in the absence of observation”

That is a dumb simplification, but the dumbness might not be so clear. So. Read More »


A lot rests on the assumption of the I, so much so that it is even hard to show that it is an assumption. Almost everything that I know comes with a degree of uncertainty, but this little bit seems certain: I am myself.

I am unable to doubt this because I look at myself. This is a reflex, and a strong one. I introspect = look inside. I know this! How could it be wrong? Even if I go into zen-style stuff about becoming one with everything, there is still an I who is doing the becoming.

In one sense, Plato’s Cave Alegory is the perfect criticism of Platonism.

There might be an element of extemporaneous simplification there, but Platonism basically is saying that the idea of a triangle is more real than a triangle made of wood. This is taking flat, featureless and unreachable things in preference to actual things. Plato’s prisoners prefer the shadows than the objects that cast them. That puts Plato as the prisoner, not the free man.

Then again, flat and featureless things are easier to parse, so you could expect the cognitive system to prefer attaching to those and thus feel Platonism as more expedient. Maybe that’s why MineCraft is such huge success. Low-res pixelated images as “more Platonic”.

A few weeks ago someone posted on hacker news an (oldish) long rant by a certain Steven Dutch against the weasel wording of post-modern philosophy of science.

For a physicist, being called solipsist is tantamount to being accused of inventing his experimental results, pretty much the worst thing one could do. For anyone in the humanities, people being their object of study, and people having a strong tendency to behave in solipsist ways, disregarding solipsism out of hand is inventing experimental results.
