Accurate facts, indisputable facts - this is what is especially unbearable for this kind of writers, and this is what is especially necessary if you want to seriously understand the complex and difficult question, quite often deliberately confusing.

We need accurate facts, available for verification, clear conclusions. Experience shows that the process of persuasion turns out to be complicated by the action of such factors as the quality and emotional acceptability of arguments for the interlocutor, their relevance for proving a particular thesis, and finally, the circumstances in which the process of persuasion takes place. Often situations will arise when seemingly indisputable arguments based on true facts turn out to be unconvincing, and arguments that boil down to; characterization of a person whose judgments are supported or s-aiairfayed.

Are my proposals supported by accurate facts and figures?

A Marxist must consider living life, the exact facts of reality, and not continue to cling to the theory of yesterday ...

In response to this, I must state the exact facts. Trummer, this is the Polish Partei vorstand, for he has not belonged to the party for a whole year. For a year now he has had no organizational connection either with the Central Committee of the Party, which was elected at the January 1912 Conference of 882, or with the so-called Organizing Commission of the Liquidators.

Which great importance Vladimir Ilyich attached to statistics, exact facts, indisputable facts, is clearly seen from his works, from those drafts, extracts and calculations that preceded these works.

The self-proclaimed prince avoided giving any exact facts and names that could be refuted as a result of verification.

Collaboration with funds mass media should be built only on the basis of accurate facts and Data. The accuracy of the information provided should be checked systematically and repeatedly. If it turns out that the facts are accidentally or deliberately distorted, the public's trust is irretrievably lost.

Along with this, during the whole of antiquity and the Middle Ages, those exact facts were slowly accumulated, which should underlie all scientific knowledge.

Such a conclusion seemed monstrous at that time, but Euler, having already in his hands an exact fact directly confirming this, did not see it for some reasons unclear to us.

The work of Duclos is fundamentally not much different from the work of Jordis and contains only more exact facts and a detailed structure problem.

Issue a directive to the Soviet and Party press to evaluate the Berlin agreement from the indicated point of view, revealing in particular detail the exact fact of the actual connection between the s.

The definitions given here random process and a stationary random process are not exact and rely more on the intuition of the reader than on exact facts.

As for the further transformation of aspartic aldehyde into protein, this is no longer a hypothesis, but a simple manipulation of formulas, based neither on exact facts, nor even on analogies. The usefulness of this kind of manipulation entirely eludes me.

Unlike previous books, where a lot of space is given philosophical questions, in this essay, written in a strict, concise language, the author is limited mainly to exact facts. So, in the preface to the first edition of this work, Agricola writes: I have allowed myself to wisely pass over in silence everything that I myself have not seen or read or have not learned from people who are trustworthy. Thus, I have indicated only what I myself saw and what, having read or heard, I myself comprehended. This work, both in terms of the brevity of its presentation and the clarity of the information given there, has the character of an instructive guide, which was subsequently preserved in books of the same type, written after Agricola and in imitation of him.
