Purchase any journal or notebook to keep a compilation of your dialectical entries.
Use a ruler to draw a straight vertical line down the center of each page, starting from the top and ending at the bottom.
Write the phrase "Author's Thoughts" on the top left half of each page, and "My Thoughts" on the top right half of each page.
Include a quote or thought from the author's text espousing the author's belief in the "Author's Thoughts" category.
Analyze that quote or excerpt of text scrupulously. Decide on if you agree or disagree, and the degree to which you agree or disagree.
Explain why you agree or disagree in the "My Thoughts" section of the text. Challenge yourself, and do not immediately accept the conventional wisdom or the author's values and beliefs.
Write down your thoughts and beliefs and ask questions, particularly why something is a certain way. The dialectical journal is a deeply philosophical tool. To attain the highest value from this exercise, be as true with yourself as possible in answering your own questions and formulating your own thoughts.
