If all that is desired is to call attention to the apparent problem in the copy text, <sic> may be used alone:

now — how <sic>we can</sic> prove or disprove anyone's theories?
Ejemplo

It is also possible, using the <choice> and <corr> elements, to provide a corrected reading:

now — how <choice>
 <sic>we can</sic>
 <corr>can we</corr>
</choice> prove or disprove anyone's theories?
