Belief of religious thought, "belief-that" instead belonged to epistemological considerations. To "believe in" someone or something is a distinct concept from "believing-that." There are at least these types of belief-in: Economic beliefs are beliefs which are reasonably and necessarily contrary to the tenet of rational choice or instrumental rationality. Studies of the Austrian tradition of the economic thought, in the context of analysis of the influence and subsequent degree of change resulting from existing economic knowledge and belief, has contributed the most to the subsequent holistic collective analysis. Insofar as the truth of belief is expressed in sentential and propositional form
Palindrome [[set (mathematics)|set]] of all palindromes in a given [[alphabet]] is a typical example of a [[formal language|language]] that is [[context-free language|context-free]], but not [[Regular language|regular]]. This means that it is impossible for a [[finite automaton|computer with a finite amount of memory]] to reliably test for palindromes. (For practical purposes with modern computers, this limitation would apply only to impractically long letter-sequences.) In addition, the set of palindromes may not be reliably tested by a [[deterministic pushdown automaton]] which also means that they are not [[LR parser|LR(k)-parsable]] or [[LL parser|LL(k)-parsable]]. When reading a palindrome from left-to-right, it is, in essence, impossible
