The first objection is, that a Flatlander, seeing a Line, sees something that must be THICK to the eye as well as LONG to the eye (otherwise it would not be visible, if it had not some thickness); and consequently he ought to acknowledge that his countrymen are not only long and broad, but also (though doubtless in a very slight degree) THICK or HIGH.
第一个反对,一个二维生物,看到线,看到的是,必须厚的眼睛,以及龙的眼睛(否则将不可见,如果没有一些厚度),因此他应该承认他的同胞不仅是长期和广泛的,而且(虽然毫无疑问,在一个很小的程度)厚或高。
