  4. ToK - Truth

  5. ToK - Truth • Does the word truth mean the same thing in each of these cases: • It is the truth that a triangle has 3 sides. • ‘There is ice at the North Pole’ is the truth. • There is real truth in that painting. • Ain’t that the truth! • This scripture is God’s truth.

  6. ToK - Truth “Truth is what stands the test of time” Einstein “A thing is not necessarily true because a man dies for it.” Wilde “Unthinking respect for authority is the greatest enemy of truth.” Einstein

  7. ToK - Truth How many legs does a dog have if you call the tail a leg? Four: calling a tail a leg doesn’t make it a leg

  8. ToK - Truth “The truth, of course, is that a billion falsehoods told a billion times by a billion people are still false.” Travis Walton

  9. ToK - Truth

  10. ToK - Truth What does it mean to say something is true?

  11. ToK - Truth To say something “is true” is much less problematic than to say itis “the truth”. Why?

  12. ToK - Truth There are three main theories of what is meant by “x is true”....

  13. ToK - Truth i. Correspondence Theory:(Going and looking)

  14. ToK - Truth ''A true proposition must correspond to or matcha state of affairs in the world.”

  15. ToK - Truth Directions - True Distances - True Shapes - True Areas - True

  16. ToK - Truth • Great circles—The shortest distance between any two points on the surface of the Earth can be found quickly and easily along a great circle. • Parallels are parallel and spaced equally on meridians. • Meridians and other arcs of great circles are straight lines (if looked at perpendicularly to the Earth's surface). • Meridians converge toward the poles and diverge toward the Equator. • It corresponds to the real world - • it is true and accurate

  17. ToK - Truth Mercator’s Projection Easier to use but how well does it correspond to reality?

  18. ToK - Truth ii. Coherence Theory:(Sitting and thinking)

  19. ToK - Truth According to this view, a proposition is true if it is consistent with all the other propositions we hold.

  20. ToK - Truth When the pieces of an argument do not fit together they are incoherent – we do not accept the argument as true.

  21. ToK - Truth If the pieces fit together they are coherent - like the pieces of a Jigsaw Puzzle

  22. ToK - Truth Coherent - but......

  23. ToK - Truth iii. Pragmatism(does it work?)

  24. ToK - Truth This is a method of philosophy in which the meaning of an idea is to be found in an examination of the consequences to which it would lead (C. S. Peirce)

  25. ToK - Truth and the truth of a proposition is measured by its practical outcome – i.e. by its consequencesrather than its origin.

  26. ToK - Truth Thus pragmatists hold that truth is not absolute, but modified as discoveries are made, and that it is therefore relative to the time, place and purpose of inquiry.

  27. ToK - Truth A proposition is true if it works or is useful in practice

  28. ToK - Truth • Examples of beliefs..... • 1. true and useful? • 2. true but not useful? • 3. not useful and not true?

  29. ToK - Truth

  30. ToK - Truth Other theories and approaches:

  31. ToK - Truth According to ‘Perspectivism' and ‘Phenomenology' there is no one truth or reality

  32. ToK - Truth A cubist approach to truth … To know what is true we need to look at many different perspectives and try to combine them in a coherent way that corresponds to reality

  33. ToK - Truth There are also those who are, to a greater or lesser degree, doubtful of our ability to attain the truth, and therefore of the possibility of any knowledge: this kind of critical outlook is called ‘Scepticism‘.

  34. ToK - Truth Relativism- argues that there is (or, we can have) nothing other than our different outlooks

  35. ToK - Truth Instead of trying to give and use a definition of absolute or universal truth, we can only study how the concept of truth has been and is being used in particular societies.Foucault

  36. ToK - Truth “Keep the company of those who seek the truth, and run away from those who have found it” Havel
