Add:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>

in your head or body tag.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Untitled Document</title>
<style>
.quotes {display: none;}​
</style>
</head>

<body>
<h2 class="quotes">first quote</h2>
<h2 class="quotes">second quote</h2>​

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
(function() {

    var quotes = $(".quotes");
    var quoteIndex = -1;

    function showNextQuote() {
        ++quoteIndex;
        quotes.eq(quoteIndex % quotes.length)
            .fadeIn(2000)
            .delay(2000)
            .fadeOut(2000, showNextQuote);
    }

    showNextQuote();

})();
</script>
</body>
</html>
