Chapter 8 General Claims

General claims are used to help us assert something in a general way about all or part of a collection. Two common words that people use when making general claims are "all" and "some." Both of these words can be ambiguous.All means "every single one, no exceptions."  Some means "at least one"  An example of a general claim using all would be : All drivers must pass their drivers' license test, before being issued a license.  An example of a general claim using some would be:  Some people prefer chocolate milkshakes to vanilla  milkshakes.  General claims can also have a contradictory. A contradictory of a claim is one that always has the opposite truth value. For example a claim would be " No men like to cook." The contradictory would be " Some men like to cook."  I use general claims in my everyday life, and sometimes they may not necessarily be true. Just yesterday I remember saying, " All Asians eat rice." The contradictory would be" Some Asians don't eat rice."
