No Suseonline we are talking Boolean algebra the language of logic.

David f well yes A does equal B because both are true.
That gate I tried to draw was an AND gate not an OR gate.
If either A or B were not true then AB would not be true.

Pelican makes the most sense in this senseless thread, when she defines 'truth' as answers to questions. No one else has bothered to define what they're writing about:
<<The correct answers are not always so easy to ascertain. Often it is opinion as your [Hasbeen's] con-men comment about climate change suggests. You cannot seriously contend that you and you only, among all the scientists and everyone else knows the 'truth' about climate change. Thank goodness for grey areas otherwise we would be run by lynch mobs.>>
While there may be some philosophic 'truths' in religious texts such as the christian bible, there are few, if any physical truths. There are no proofs of the existence of the biblical Jesus, for example, despite the searches of scholars in all the relevant documents of the Roman occupation of Palestine. It seems odd that they recorded the price of grain and the number of sheep and goats as well as weather conditions, but failed to mention a miracle or two.

A + B = AB?

Only in Boolean logic, not in logical logic!!

A x B generally equals AB in mathematical and scientific formulae.

So… does this make the Booleans illogical (and/or untruthful)?

Or does it make scientists and mathematicians illogical?

Dear runner,

I prefer csteele to Jesus. csteele submits to questioning. He does not make arrogant statements such as "I am the way, the truth, the life." He does not make intolerant statements such as, "Only through me can thou enter the kingdom of heaven." csteele does not claim sole possession of the truth. csteele has not accumulated masses of intolerant followers who massacre people when they refuse to accept the Christian mumbojumbo. csteeele does not demand that people worship him. I feel that I could have a reasonable conversation with csteele if I ever met him. I don't have that feeling about the Jesus of the Bible. Of course it is possible that Jesus never said anything that is attributed to him or even existed. The New Testament contains a number of fairy tales which were written after Jesus was supposed to have died. The Jesus of the Bible is probably a composite of various legendary wonder workers.

Opinion and belief are often confused with truth. One beauty of science is that it doesn't deal in truth. It deals in hypotheses and evidence. Any scientific hypothesis or theory must be abandoned if there is evidence that it is invalid.

I agree, csteele never claimed to be the son of God nor did anybody, to my knowledge, call him the “son of God”, whatever that might mean to a non-Christian.

Science indeed does not “deal in truth”, although the question of verisimilitude (or, better, adequacy) of a scientific theory - when dealing with physical reality as such (not just with some restricted family of phenomena) - is more complicated than valid or invalid, depending on evidence: Newtonian physics was not abandoned and it is certainly “valid” in many situations where the application of gravitation theory or QM would be too clumsy, inadequate for practical purposes.

There is also a difference between TRUTH - which makes sense only in trivial everyday situations, or as a subject of metaphysics/religion - and TRUE STATEMNTS, which are either formal (in logic or mathematics) or subject to generally accepted evidence.

My dear Mr Opinion, how typical of a humanities type. You let them up from the bottom of the garden for a minute, & they suddenly think they have some idea of the real world.

It is a damn good thing our building codes, were not designed by your Hocus Pocus experts, or our buildings would all have fallen down all ready.

I do find it interesting that you can not differentiate between the designer, & the bloke who puts the design together. Not surprising but interesting none the less. This would perhaps indicate why your lot still can’t sort the good from the bad or the ugly.

The only thing universities should be teaching is the provable. Knowledge that expands continually on it’s proven base, which must be taught to sustain our society.

Your subjects, where after a couple of thousands of years of talking, you still have gained nothing, belongs in the Druids circle. You should give a little thanks to the engineer/ physicists, who has developed a society rich enough to allow those with your interests to spend lifetimes meditating on their navel, with out ever achieving anything at all.
