Try Derek Parfit. His book "Reasons and Persons" touches on some fascinating questions (identity) with clear thought experiments that actually reach the level of clarity this article suggests.
I would definitely not say "Reasons and Persons" is clear. It might be precise (I personally don't think so, I think he makes tons of subtle mistakes), but it's at least not clear. It's full of ideas like "rational irrationality" which is at best a poor choice of naming, IMO.
Without context, sure, but when we're talking specifically about the precision of expression, I don't think so. Some philosophers operate closer to mathematical precision than others, and when those sorts of precision-oriented philosophers screw up their precision, it's a bigger problem. In Reasons and Persons, Parfit jumps through hoops to make his statements precise but ultimately trips all over himself (in my opinion).
