Slate Slate Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism. It is the finest grained foliated metamorphic rock. Foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of metamorphic compression. The foliation in slate is called "slaty cleavage". It is caused by strong compression causing fine grained clay flakes to regrow in planes perpendicular to the compression. When expertly "cut" by striking parallel to the foliation, with a specialized tool in the quarry, many slates
Value-form subjects, and therefore human relations without values or valuations of some sort do not exist. At best one could say (as Marx did), that the type of value or valuation can change. A third objection is that people can distinguish quite well between the means/ends rationality of commerce, and non-commercial relationships. Therefore, it is simply an inaccurate and false subjective opinion to claim that there exists some kind of "monumental domination" of commercial relationships over people's lives, because that is not true—except perhaps for people who are obsessively focused on trading relationships. What is ignored is that markets can offer
