EDITORIAL: The gift of clear thinking for free.

Philanthropy has never gone out of fashion. It commonly involves donations of various kinds, but Professor Brendan Myers from Quebec, Canada, is donating something even more precious, the ability for people to think for themselves.


Brendan Myers had written the first edition of the book and printed it as a low cost book to give access to as many people as possible. Recently he went to Kickstarter and successfully raise funds for an updated and expanded second edition.


The motivation for this work can be found in this quote:

Have courage to think for yourself! That is the motto of the Enlightenment.

(Immanuel Kant, "What is Enlightenment?" 1784)

In order to bring our "post-truth" society back to reason, Brendan Myers has put the PDF version for free here:

For those wanting a paperback version, you may buy it at Amazon for US$9.95 plus postage here:

PD urges educators to make use of this generosity to give the gift of thinking to their students.
