My question is regarding the case of a dependent participle. In the impersonal construction -- δοκεῖ μοι *ἐμὲ* καλῶς ποιεῖσαι ἑκόντα βοηθοῦντά σοι,
it seems to me that I do well if I willingly come to your aid, -- we have dependent participle and modifiers in the accusative.
In the personal -- δοκῶ μοι κακὰ ἐργάζεσθαί σε μὴ βοηθῶν σοι, I think I do you harm if I don't help you, -- they are in the nominative.
What happens when δοκεῖ μοι is not impersonal. Does it then have nom. part.?
And in any case, why isn't the participle in dative case for μοι?
* edited again. sorry, there's no εἶναι when there's already an inf. standing for a verb other than εἰμί, γίγνομαι, etc.*
