'''Fuzzy logic''' is a relatively new chapter of formal logic whose aim is to formalize the reasonings involving predicates that are vague in nature (as an example ''small'', ''near'', ''similar''). An example of such kind of reasoning is

Further examples of reasonings involving vague predicates are in the item ''[[Paradoxes and fuzzy logic]]'' and in the section ''Fuzzy logic with no truth-functional semantics''. The main tool for fuzzy logic is the notion of a ''[[fuzzy subset]]'' since a vague predicate is interpreted by a fuzzy subset. Notice that in literature the name ''"fuzzy logic"'' also denotes a large series of topics based on an informal usage of the notion of a fuzzy subset and which are usually devoted to applications.

As a matter of fact, fuzzy logic is an evolution and an enlargement of [[multi-valued logic]] since all the definitions and results in the literature on multi-valued logic are also considered in fuzzy logic. In particular, as in multi-valued logic, the starting point is a fixed ''valuation structure'', i.e. a bounded [[lattice (order)|lattice]] ''L'' equipped with suitable operations to interpret the logical connectives. The minimum 0 means ''''False'''', the maximum 1 means ''''True'''', the remaining elements are interpreted as intermediate truth values. The following is the main class of valuation structures (see Hájek 1998, Novák et al. 1999 and Gottwald 2005) corresponding to the connectives <math>\wedge</math> and <math>\rightarrow </math>.

Scalawag


In American history, a Scalawag was a Southern white who joined the Republican party during Reconstruction. They formed a coalition with Freedmen (blacks who were former slaves) and Northern newcomers (called Carpetbaggers) to take control of their state and local governments at various times, 1867-1877. Men who had not supported the Confederacy were eligible to take the "ironclad oath," as required by the Reconstruction laws in 1867 to vote or hold office. In the 1870s, many switched from the Republican Party to the conservative-Democrat coalition, called the Redeemers, which defeated and replaced all the state Republican regimes by 1877.

Their primary interest was in supporting a party that would build the South on a broader base than the plantation aristocracy of ante-bellum days. They found it expedient to do business with blacks and carpetbaggers; increasingly after 1872 they returned to the Democratic party as it gained sufficient strength to be a factor in Southern politics.[1]
