What is Truth

The words true and false have been tossed around rather blithely in this chapter. It is now appropriate to dehne these terms more pricisely. Regardless of the meaning of truth in the broader, philosophical sense, truth in Perl boils down to four very simple rules  

The various numeric and string comparison tests that were illustrated in the previous section evaluate to 1 when true and to the undefined value when false. 

Before the loop begins, the program creates a variable named count and sets its value to 1. The while loop test checks whether count is less than or equal to 10 and executes the two statements contained in the only braces as long as this condition holds true. The hrst statement prints out the cmrent value of count, and the second increments the variable by 1. The first time the while statement is encountered, count was set to 1, so the block is executed. The second time, count is 2, and the block is executed again. This continues imtil count is 6, at which point the test is no longer true (because count is greater than 5) and the loop terminates. The output for the program is quite simply 

In the same way that unless reverses the sense of the If statement, until can be used as an alternative to while. Until loops will execute the contents of a block until a certain test becomes true. The counting program could then be rewritten as follows, to yield the same output

From a religious point of view, what is truth Use examples from two different religions to support your answer. 

I had a chance to do this in the spring of 1989, when one of my friends, who had left the liberal FDP shortly before to join the Repub-likaner, addressed the Holocaust issue in one of our discussions. He recommended that I read the book Was ist Wahrheit, (What is Truth) by the socialist Frenchman, Professor Paul Rassinier.30 This may be regarded as the first fully revisionist book ever published. It deals with the supposed extermination of the Jews from the point of view of a former member of the French Resistance who had been incarcerated by the Germans in several concentration camps during WWII. 

Thank you for your letter regarding the planned 283a. The Leuchter Report which you sent me is already known to me. I must say, however, that the personal recollections of so many witnesses who described the atrocities of Auschwitz impress me more than the expositions of the Leuchter Report I do, however, fully agree with you on the point that only science, not a trial judge, can determine what is truth and what is falsehood. ... 

These philosophical difficulties are central to the structural designe problem. If we can only treat a scientific theory as if it were true, by how muc does it differ from the truth What is truth How can we increase the econon and efficiency of the structures we build without knowing what truth is The must be a limit to the economic savings we can make, if we are not to reduce tl safety of our structures beyond acceptable bounds. One of the philosophic problems central to our engineering problems is perhaps not so much what truth, but how can we measure how near we are to it ... 

Medicinal chemistry, like truth, defies ready definition. The iracticing organic chemist as a rule knows operationally what is, ir more often what is not, medicinal chemistry. He would be 1,-ird pressed, however, to set down on paper a rigorous defini-ion of that discipline. 

Here, after having found the Path of Life beyond all lives and all deaths, Gautama—the Buddha—decided to set the Wheel of the Doctrine in motion and to give Man the teaching of the Noble Truths, which embodies the true vision of What IS. And also to teach about the Path that leads from Darkness to Light from Illusion to Truth from Death to Eternity. 

As discussed in the previous section the standard error simply provides indirect information about reliability, it is not something we can use in any specific way, as yet, to tell us where the truth lies. We also have no way of saying what is large and what is small in standard error terms. We will, however, in the next chapter cover the concept of the confidence interval and we will see how this provides a methodology for making use of the standard error to enable us to make statements about where we think the true (population) value lies. 

If this is accepted, the two criticisms add up to a formidable objection to the theory that the line dividing S from is the line dividing what is not conscious from what is conscious. It is no good protesting that the objection is captious because it hammers a theory for breaking down in a few exceptional cases. That is not the situation here. For however much truth there may be in this theory, its breakdowns are very common. It follows that, whatever the importance of consciousness, there must be another factor at work and it is possible that the line dividing S from ought to be based on that other factor. 

In the opinion of Liebig, the experiments of Lawes and Gilbert, so far from disproving the mineral theory, afford, cn the contrary, the strictest and most satisfactory proof of its truth. The reader is referred to Liebig s able work for a clear and distinct view of what Is really his mineral theory, and to a paper by the same author in defence of his views, in the seventeenth volume of the. Journal of the English Agricultural Society. 

The defenders of democracy sit on the accuser s bench. When a democratic state takes upon itself the power to determine what the truth is, it is no longer a democracy , the attorney admonished the State Attorney and court.
