613 Intro|              attempt to explain false opinion without having explained

642 Intro|            act. Here the idea of true opinion seems to be a right conclusion

676 Text |             he not allow that his own opinion is false, if he admits that
677 Text |          false, if he admits that the opinion of those who think him false

689 Text |              I agree with you in that opinion.~SOCRATES: The reason why
690 Text |           organs. For that was my own opinion, and I wanted you to agree
691 Text |               say, Socrates, that all opinion is knowledge, because there
692 Text |          because there may be a false opinion; but I will venture to assert,
693 Text |                that knowledge is true opinion: let this then be my reply;
694 Text |                Are there two sorts of opinion, one true and the other
695 Text |               the discussion touching opinion?~THEAETETUS: To what are
696 Text |                How there can be false opinion—that difficulty still troubles
697 Text |              Do we not speak of false opinion, and say that one man holds
698 Text |              false and another a true opinion, as though there were some
699 Text |            not say that he who has an opinion, must have an opinion about
700 Text |              an opinion, must have an opinion about something which he
701 Text |                When a man has a false opinion does he think that which
702 Text |       SOCRATES: Where, then, is false opinion? For if all things are either
703 Text |              unknown, there can be no opinion which is not comprehended
704 Text |             alternative, and so false opinion is excluded.~THEAETETUS:
705 Text |              so.~SOCRATES: Then false opinion has no existence in us,
706 Text |             we not suppose that false opinion or thought is a sort of
707 Text |              truly said to have false opinion.~THEAETETUS: Now you appear
708 Text |               then he has truly false opinion.~SOCRATES: I see, Theaetetus,
709 Text |              are satisfied that false opinion is heterodoxy, or the thought
710 Text |             doubt, this is called her opinion. I say, then, that to form

717 Text |           which I cannot form a false opinion about you and Theodorus,
718 Text |              possibility of erroneous opinion is, when knowing you and
719 Text |           then ‘heterodoxy’ and false opinion ensues.~THEAETETUS: Yes,
720 Text |               described the nature of opinion with wonderful exactness.~
721 Text |           which, as we now say, false opinion may arise, when knowing
722 Text |             perceived; in these alone opinion turns and twists about,
723 Text |              natures which have false opinion; for when they see or hear
724 Text |          admit the existence of false opinion in us?~THEAETETUS: Certainly.~
725 Text |      Certainly.~SOCRATES: And of true opinion also?~THEAETETUS: Yes.~SOCRATES:
726 Text |          there are these two sorts of opinion?~THEAETETUS: Undoubtedly.~
727 Text |          indeed discovered that false opinion arises neither in the comparison

729 Text |            the non-existence of false opinion, because otherwise the same
730 Text |            true.~SOCRATES: Then false opinion cannot be explained as a
731 Text |             to say, either that false opinion does not exist, or that
732 Text |                but he may get a false opinion about it; for he may have
733 Text |              not deceived, and has an opinion of what is, and thus false
734 Text |               and thus false and true opinion may exist, and the difficulties
735 Text |             another ever become false opinion?~THEAETETUS: What do you
736 Text |            thus he would have a false opinion from ignorance, but a true
737 Text |           ignorance will have a false opinion—am I right?~THEAETETUS:
738 Text |             think that he has a false opinion?~THEAETETUS: Of course not.~
739 Text |                He will think that his opinion is true, and he will fancy
740 Text |            wrong in seeking for false opinion until we know what knowledge
741 Text |             then, the nature of false opinion?~THEAETETUS: I cannot but
742 Text |             was said by us to be true opinion; and true opinion is surely
743 Text |             be true opinion; and true opinion is surely unerring, and
744 Text |           them is making them have an opinion?~THEAETETUS: To be sure.~
745 Text |             report they attain a true opinion about them, they judge without

750 Text |                any one forms the true opinion of anything without rational
751 Text |          allow and maintain that true opinion, combined with definition
752 Text |              from definition and true opinion? And yet there is one point
753 Text |               therefore, agree in the opinion of him who says that the
754 Text |             the statement, that right opinion with rational definition
755 Text |           verbs and nouns, imaging an opinion in the stream which flows
756 Text |            all those who have a right opinion about anything will also
757 Text |           explanation; nor will right opinion be anywhere found to exist
758 Text |               name—that would be true opinion, and not knowledge; for
759 Text |             until, combined with true opinion, there is an enumeration
760 Text |               we might also have true opinion about a waggon; but he who
761 Text |          rational explanation to true opinion, and instead of opinion
762 Text |               opinion, and instead of opinion has art and knowledge of
763 Text |               correctly, he has right opinion?~THEAETETUS: Clearly.~SOCRATES:
764 Text |               admit that he has right opinion, he will still be without
765 Text |         explanation, as well as right opinion, for he knew the order of
766 Text |              is such a thing as right opinion united with definition or
767 Text |        maintains knowledge to be true opinion combined with rational explanation?
768 Text |              But he, who having right opinion about anything, can find
769 Text |           which before he had only an opinion.~THEAETETUS: Yes; that is
770 Text |           suppose myself to have true opinion of you, and if to this I
771 Text |           have knowledge, but if not, opinion only.~THEAETETUS: Yes.~SOCRATES:
772 Text |         SOCRATES: But when I had only opinion, I had no conception of
773 Text |               you to-morrow the right opinion will be re-called?~THEAETETUS:
774 Text |            true.~SOCRATES: Then right opinion implies the perception of
775 Text |               or explanation to right opinion? If the meaning is, that
776 Text |                that we should form an opinion of the way in which something
777 Text |           supposed to acquire a right opinion of the differences which
778 Text |               we have already a right opinion of them, and so we go round
779 Text |               and not merely ‘have an opinion’ of the difference, this
780 Text |           argument will answer ‘Right opinion with knowledge,’—knowledge,
781 Text |           reply should only be, right opinion with knowledge of difference
782 Text |            neither sensation nor true opinion, nor yet definition and
783 Text |        accompanying and added to true opinion?~THEAETETUS: I suppose not.~
