This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

the section in article class is defined so, that the paragraph after it is not indented –  Zarko Oct 30 '12 at 16:13
Welcome to TeX.SE. The point of indenting a paragraph is to make it obvious that this is the start of a new paragraph. After a \section it is obvious that it is the start of a new paragraph so no indent is added. –  Peter Grill Oct 30 '12 at 16:17

That's a common rule for indent in some languages: it's indent only the second and other paragraph.

If you want indent first paragraph too: \usepackage{indentfirst}.
