from the collected kinds. At first he starts with the use of a mundane model (
Angler), which shares some qualities in common with the target kind (
Sophist). This common quality is the certain expertise (
techne) at one subject. Then through the method of collection of different kinds (farming, caring for mortal bodies, for things that are put together or fabricated and imitation) he tries to bring them together (

) into one kind, which he calls
productive art. The same is true with the collection of learning, recognition, commerce, combat and hunting, which can be deduced into the kind of
acquisitive art.
After these two collections he proceeds to the division of the expertise into
production and
acquisition, and then he tries to find out to which of these two sub-kinds the angler belongs (classification), which means acquisition. By following the same method, deduction through collection, he divides the acquisition in
possession taking and
exchanging goods, to which sophistry belongs. After many successive collections and divisions he finally arrives at the definition of the model (Angler). Throughout this process Plato discovers many kinds and sub-kinds (hunting, aquatic-hunting, fishing, strike-hunting).
After the verbal explanation of the model (definition), he tries to find out what the model and the target kind share in common (sameness) and what differentiates them (difference). Through this comparison, and after having been aware of the different kinds and sub-kinds, he can classify sophistry also among the other branches of the ‘tree’ of division of expertise as follows:
1. production, hunting by persuasion and money-earning, 2.acquisition, soul wholesaling, 3. soul retailing, retailing things that others make, 4. soul retailing, retailing things that he makes himself, 5. possession taking, competition, money-making expertise in debating.
Throughout the process of comparison of the deduced kinds through his method of collection,

, so to say: quantity, quality, relation, location, time, position, and etc.
After having failed to define sophistry, he attempts a final deduction through the collection of the five definitions of sophistry. Since these five definitions share in common one quality (sameness), which is the
imitation, he finally qualifies sophistry as
imitation art. Following the division of the imitation art in
copy-making and appearance-making, he discovers that sophistry falls under the
appearance-making art, namely the Sophist imitates the wise man. However, in order that his conclusion is irrefutable

said. Furthermore,
Being is a distinct kind, which all existing things share in common.
Sameness is a distinct kind that all things, which belong to the same kind or genera share with reference to a certain attribute, and due to which deduction through collection is possible.
Difference is a distinct kind that makes things of the same kind not to be identified , therefore it enables us to proceed to their division. The knowledge of these five Great Kinds and their ability of blending is the characteristic of the Philosopher, since it is equivalent to expertise in

. Finally, so-called
Not-Being is not the opposite of
Being but simply different from it; for instance, the statement
this is not black does not necessarily indicate whiteness—it asserts no preference among non-black colors. Therefore the negation of
Being is identified with the
Difference, since negative predication indicates something different (an unlimited range) from the predicate. Not-being is difference, it is not the opposite of Being.
Following these conclusions, the ‘true statement’ can be distinguished from the ‘false’ one, since each statement consists of a verb and a name. The name refers to the subject, namely the statement is about something, because a thought or a speech is always about something, and it cannot be about nothing (
Not-Being). The verb is the sign of the action that the subject performs (
poiein) or the action being performed to or on the subject (
paschein). When the verb states something that is about the subject, namely one of his properties, then the statement is true. While when the verb states something that is
different (
it is not) from the properties of the subject, then the statement is false. In this way

associates the Non-Identity (NI) premise with Negative Predication (NP).
‘
Theaetetus is flying’ is false while ‘
Theaetetus is sitting’ is true, because the predicate ‘flying’ is different from the actual predicate of Theaetetus, which is ‘sitting’. Therefore, in order to examine whether a statement is false or true, we simply need to find at least one property the subject possesses that is different from the one that the predicate specifies . It is plausible then, that ‘
things that are not (appearing and seeming) somehow are’, and so it is also plausible that the sophist produces false appearances and imitates the wise man.
Final definition
After having solved all these puzzles, that is to say the interrelation between being, not-being, difference and negation, as well as the possibility of the ‘appearing and seeming but not really being’, the Visitor from Elea can finally proceed to define sophistry. In other words,
sophistry is a productive art, human, of the imitation kind, copy-making, of the appearance-making kind, uninformed and insincere in the form of contrary-speech-producing art.
Interpretations
Since Plato wrote the
Statesman after the
Sophist, while he never wrote the dialogue
Philosopher, many scholars argue that Plato challenges the audience to search for the definition of the philosopher themselves, by applying the method of inquiry and definition shown in those two dialogues. However, this does not mean that one can simply extend the method in a mechanical way to the investigation of the philosopher, but he only shows us how one can proceed in such philosophical enquiries.
Aristotle picks up a number of themes dealt with in the
Sophist in his own work
De Interpretatione. Among these are the required parts of a statement (names and verbs) as well as affirmations and denials.
