WebFeb 19, 2013 · 13. To understand how to represent Booleans in lambda calculus, it helps to think about an IF expression, "if a then b else c". This is an expression which chooses the first branch, b, if it is true, and the second, c, if it is false. Lambda expressions can do that very easily: lambda (x).lambda (y).x. will give you the first of its arguments, and.
