<h2>About ER22x</h2>
<p>Justice is a critical analysis of classical and contemporary theories of justice, including discussion of present-day applications. Topics include affirmative action, income distribution, same-sex marriage, the role of markets, debates about rights (human rights and property rights), arguments for and against equality, dilemmas of loyalty in public and private life. The course invites students to subject their own views on these controversies to critical examination.</p>
<p>The principle readings for the course are texts by Aristotle, John Locke, Immanuel Kant, John Stuart Mill, and John Rawls. Other assigned readings include writings by contemporary philosophers, court cases, and articles about political controversies that raise philosophical questions.</p>
<!--
<p>The assigned readings will be freely available online. They are also collected in an edited volume, <emph>Justice: A Reader</emph> (ed. Michael Sandel, Oxford University Press). Students who would like further guidance on the themes of the lectures can read Michael Sandel, <emph>Justice: What’s the Right Thing to Do?</emph> (Recommended but not required.)

<h2>Frequently Asked Questions</h2>
<article class="response">
<h3>How much does it cost to take the course?</h3>
<p>Nothing! The course is free.</p>
</article>
<article class="response">
<h3>Does the course have any prerequisites?</h3>
<p>No. Only an interest in thinking through some of the big ethical and civic questions we face in our everyday lives.</p>
</article>
<article class="response">
<h3>Do I need any other materials to take the course?</h3>
<p>No. As long as you’ve got a computer to access the website, you are ready to take the course.</p>
</article>
<article class="response">
<h3>Is there a textbook for the course?</h3>
<p>All of the course readings that are in the public domain are freely available online, at links provided on the course website. The course can be taken using these free resources alone. For those who wish to purchase a printed version of the assigned readings, an edited volume entitled, Justice: A Reader (ed., Michael Sandel) is available in paperback from Oxford University Press (in bookstores and from online booksellers). Those who would like supplementary readings on the themes of the lectures can find them in Michael Sandel's book Justice: What's the Right Thing to Do?, which is available in various languages throughout the world. This book is not required, and the course can be taken using the free online resources alone.</p>
</article>
<article class="response">
<h3>Do I need to watch the lectures at a specific time?</h3>
<p>No. You can watch the lectures at your leisure.</p>
</article>
<article class="response">
<h3>Will I be able to participate in class discussions?</h3>
<p>Yes, in several ways: </p>
<ol>
<li><p> Each lecture invites you to respond to a poll question related to the themes of the lecture. If you respond to the question, you will be presented with a challenge to the opinion you have expressed, and invited to reply to the challenge. You can also, if you wish, comment on the opinions and responses posted by other students in the course, continuing the discussion.</p></li>
<li><p> In addition to the poll question, each class contains a discussion prompt that invites you to offer your view on a controversial question related to the lecture. If you wish, you can respond to this question, and then see what other students have to say about the argument you present. You can also comment on the opinions posted by other students. One aim of the course is to promote reasoned public dialogue about hard moral and political questions. </p></li>
<li><p> Each week, there will be an optional live dialogue enabling students to interact with instructors and participants from around the world.</p></li>
</ol>
</article>
<article class="response">
<h3>Will certificates be awarded?</h3>
<p>Yes. Online learners who achieve a passing grade in a course can earn a certificate of mastery. These certificates will indicate you have successfully completed the course, but will not include a specific grade. Certificates will be issued by edX under the name of HarvardX, designating the institution from which the course originated. </p>
