Your entire post is predicated on a simple straw man argument. You claim that Aristotle is against method chaining because he isn't "used to" it. Frankly, I think that's condescending and silly, but it's also wrong. The argument isn't that it's hard to "get used to," but that even if you are intimately familiar with it, it's hard to understand code that uses it. Take this code example:

$foo->bar(2)->baz(3)->qux;

Versus this one:

my $bar = $foo->bar(2); $bar->baz(3); $bar->qux;

The first requires a lot more effort to decipher than the 2nd. If you're not familiar with the methods and their return values in the 1st snippet, you'd have to look them up in the documentation. Even if you knew the method return values off the top of your head, you'd have to trace the chain carefully to make sure you understand what's going on.

In the 2nd, if you didn't know the return values, you could take a reasonable guess, and probably be right. And if you did know the return values, then it's obvious what's going on without any thought required at all. This is called self documenting code, and it's generally something we strive for.
