In this chapter, I propose to study the relationships between political views (or at least the interest of engineers for political discussion) and some of the issues discussed in the field of engineering ethics. I will also study the relationship between religious commitment (belief and practice) and this set of issues. This reflection is based of the results of a survey with 3901 French graduate engineers Although this survey is mostly meaningful in its specific national context, it supports an idea that is worth outside this of this context: engineering ethics is neither politically value-free and nor religious value-free.
