When an important new concept or new term is introduced for the first time in an article, it should be placed in '''bold faced type'''. For example: Descartes' '''methodological skepticism''' was based on reason and on the capacity to doubt. Words or phrases may be placed in ''italics'' for emphasis. For example: The term scientonomy refers to the ''science of science''. Titles of books should also be ''italicized''. For example: Thomas Kuhn wrote ''The Structure of Scientific Revolutions''.
== Use of subheadings ==The major headings for an article are pre-specified according to the type of article you are writing. To add a subheading, enclose your subheading in three levels of equal signs: <code><nowiki>== Use of subheadings = Newton on Mathematics and Natural Philosophy ===</nowiki></code> If you need deeper levels of subheadings, add another set of equals signs for each new level of subheadings.
