6.1-2
Speaking and thinking needs be existing; for there is Being and Nothing does not exist. These I demand from you to consider. 

8.3-10, 22-25, 29-30, 34-36

(…) Being unborn is undestroyable, for it is intact and unshakable and endless; neither sometime was nor will it be, for it exists now all together, one, continuous; for what birth of it can you seek? How, whence did it grow? Nor from non-being will I let you say or think. For what does not exist is unspeakable and unthinkable. And what need might have moved it, later or earlier, to start from nothing and grow? (…)

Nor can it be devided since all is alike; neither somewhere is better, since that would disturb it being cohered, nor worse, but it is all full of being. It is coherent all of it, because being loves to draw near being. (…)

The same, and in the same conditions remaining, lies by itself and thus stable there remains. (…)

The same is thinking and the cause of meaning's being. For without being, wherein it has been spoken, you won't find thinking.

6.1-2
χρὴ τὸ λέγειν τε νοεῖν τ΄ ἐὸν ἔμμεναι· ἔστι γὰρ εἶναι͵ μηδὲν δ΄ οὐκ ἔστιν· τά σ΄ ἐγὼ φράζεσθαι ἄνωγα.    

8.3-10, 22-25, 29-30, 34-36

(…) ἀγένητον ἐὸν καὶ ἀνώλεθρόν ἐστιν͵ ἐστι γὰρ οὐλομελές τε καὶ ἀτρεμὲς ἠδ΄ ἀτέλεστον· οὐδέ ποτ΄ ἦν οὐδ΄ ἔσται͵ ἐπεὶ νῦν ἔστιν ὁμοῦ πᾶν͵ ἕν͵ συνεχές· τίνα γὰρ γένναν διζήσεαι αὐτοῦ; πῆι πόθεν αὐξηθέν; οὐδ΄ ἐκ μὴ ἐόντος ἐάσσω φάσθαι σ΄ οὐδὲ νοεῖν· οὐ γὰρ φατὸν οὐδὲ νοητόν ἔστιν ὅπως οὐκ ἔστι. τί δ΄ ἄν μιν καὶ χρέος ὦρσεν ὕστερον ἢ πρόσθεν͵ τοῦ μηδενὸς ἀρξάμενον͵ φῦν; (…)

οὐδὲ διαιρετόν ἐστιν͵ ἐπεὶ πᾶν ἐστιν ὁμοῖον· οὐδέ τι τῆι μᾶλλον͵ τό κεν εἴργοι μιν συνέχεσθαι͵ οὐδέ τι χειρότερον͵ πᾶν δ΄ ἔμπλεόν ἐστιν ἐόντος. τῶι ξυνεχὲς πᾶν ἐστιν· ἐὸν γὰρ ἐόντι πελάζει. (…)

ταὐτόν τ΄ ἐν ταὐτῶι τε μένον καθ΄ ἑαυτό τε κεῖται χοὔτως ἔμπεδον αὖθι μένει. (…)

ταὐτὸν δ΄ ἐστὶ νοεῖν τε καὶ οὕνεκεν ἔστι νόημα. οὐ γὰρ ἄνευ τοῦ ἐόντος͵ ἐν ὧι πεφατισμένον ἐστιν͵ εὑρήσεις τὸ νοεῖν (…)
