Whatever we knock against and get hold of we shall be taking for the thing we want, because the truth is hidden from us. Even if a mere piece of luck brings us straight to it, we shall have no grounded conviction of our success; there are so many similar objects, all claiming to be the real thing.
οἷς ἂν τύχωμεν προσπταίοντες καὶ ὅ τι ἂν πρῶτον ἐς τὰς χεῖρας ἔλθῃ, τοῦτο εἶναι τὸ ζητούμενον ὑπολαμβάνοντες διὰ τὸ μὴ εἰδέναι τἀληθές. εἰ δὲ καὶ εὕροιμεν ἄλλως κατά τινα ἀγαθὴν τύχην περιπεσόντες αὐτῷ, οὐχ ἕξομεν βεβαίως εἰδέναι εἰ ἐκεῖνό ἐστιν ὃ ζητοῦμεν. πολλὰ γάρ ἐστιν ὅμοια αὑτοῖς, λέγοντα ἕκαστον αὐτὸ εἶναι τἀληθέστατον.
