I've recently been preparing a couple of items for presentation. The one project has me returning to my monograph, so as to highlight the principal aim of that project and to consider where my research programme might be moving. In this preparation I have once again turned to my interest in the philosophy of technology, and specifically, the writings of Gabriel Marcel. Here is what Marcel has to say about technique, from an excerpt recorded in my monograph:

The term technique refers to the tasks performed and/or procedures constructed that, with order and precision, regulation and control, intend to attain a particular end and/or manufacture a particular commodity. In addition, synonyms will be used readily, including but not limited to technologies, models, systems, frameworks, and tools. Regarding the meaning of technique, Gabriel Marcel offer the following:
What is a technique? It is a group of procedures, methodologically elaborated, and consequently capable of being taught and reproduced, and when these procedures are put into operation they assure the achievement of some definite concrete purpose (Marcel, Man against Mass Society, translated by GS Fraser [South Bend: St. Augustine's Press, 2008], p. 62).
Insofar as a technique is something that we can acquire, it may be compared to a possession—like a habit, which is at bottom itself already a technique. And we can at once see that if a man can become the slave of his habits, it is equally probable that he can become prisoner of his techniques.
