  Slate - LoveToKnow 1911
Cleavage is thus a superinduced structure, and its explanation is to be found in the rearrangement of the minerals, and the development of a certain degree of crystallization by pressure acting on the rock.
Slates belong mostly to the older geological systems, being commonest in Pre-Cambrian, Cambrian and Silurian districts, though they may be found of Carboniferous or even of Tertiary age, where mountain-building processes have folded and compressed these more recent formations.
In other cases, especially near mineral veins, slates are filled with fl needles of tourmaline or are bleached to pale grey and white colours, or are silicified and impregnated with mineral ores.

The Blank Slate: The Modern Denial of Human Nature is a best-selling 2002 book by Steven Pinker arguing against tabula rasa models of psychology, arguing that the human mind is substantially shaped by evolutionary psychological adaptations.
