The concepts of specification and formalization, as relevant to the development of programs, are introduced and discussed. It is found that certain arguments given for using particular formal modes of expression in developing and proving programs correct are invalid. As illustration a formalized description of Algol 60 is discussed and found deficient. Emphasis on formalization is shown to have harmful effects on program development, such as neglect of informal precision and simple formalizations. A style of specifications using formalizations only to enhance intuitive understandability is recommended.
