IJAHP: Mu/ On the Nature of Essays International Journal of the Analytic Hierarchy Process 147 Vol. 7 Issue 2 2015 ISSN 1936-6744 http://dx.doi.org/10.13033/ijahp.v7i2.345 August 2015 On the Nature of Essays Dear IJAHP Reader: This is our second issue in our new publication frequency of three issues a year. It includes, as usual, several articles on the theory and practice of AHP/ANP. Furthermore, it also includes a thought-provoking essay by Claudio Garuti titled “Parallel Between Space Geometry & Decision Making Space.” A comment on our policy for essays may be in order. Aldous Huxley, a famous essayist, used to say that an essay is a literary device to say almost everything about almost anything. We agree with this definition and for this reason you will notice a great variety of topics have been published in the essay section of this journal. An essay does not follow the standard double-blind review process, but is accepted/rejected by the editorial team based on its relevance, originality and thought-provoking potential. In other words, it is accepted based on trust in the author. In any case, we prefer to err on the side of creativity rather than on the side of clarity or, God forbid, even accuracy. Our main goal for an essay is to get the reader to think in a different way. If you think you have anything to say about something that fulfills the above criteria, you are welcome to submit it to our journal. Thanks for your support and enjoy this issue!
