159) take this question of certainty a step further, by stating that even though we do not have absolute certainty, this does not mean we know nothing. At times one fails to understand why things are the way they are. The reason is that our senses fail us, and because of the lack of relevant data or our reasoning is incorrect (Dew & Foreman, 2014, p. 159). There also is the factor that our minds are unable to go “as far as we would like to go” (Dew & Foreman, 2014, p. 159). There is a high level of certainty called logic and absolute certainty (Dew & Foreman, 2014, p. 161). At this level, belief is impossible to doubt. Some examples are: logical statements, self-evident truths, or many mathematical propositions” (McGrath as cited in Dew & Foreman, 2014, p. 161). Such examples are “2 +2 =4, or all triangles have three sides” (McGrath as cited in Dew & Foreman, 2014, p. 161). It is impossible for these to be untrue. Another level is probabilistic certainty, for example “The sun will rise tomorrow” (McGrath as cited in Dew & Foreman, 2014, p. 161). Even though this is universal truth, it is possible that tomorrow the sun will not rise. Therefore, one cannot claim certainty that this will happen (McGrath as cited in Dew & Foreman, 2014, p. 161). Another level is called “sufficient certainty” (McGrath as cited in Dew & Foreman, 2014, p. 162). When one has sufficient certainty, it is because there is good evidence that the belief is true and there is no one to defeat the belief (Dew & Foreman, 2014, p.
