Dear Harold,

why not take the chance and substitute "tacit" with "implicit" in the diagram. This would avoid epistemological pitfalls. Here is a machine translation, why it would be sensible: http://translate.google.de/translate?sl=auto&tl=en&js=n&prev=_t&hl=de&ie=UTF-8&layout=2&eotf=1&u=http%3A%2F%2Fwww.karsten-ehms.de%2Fbooks%2F2010-Ehms-Dissertation-2.htm%2350651139_pgfId-1011758&act=url
("silent knowledge" to be substitued with "tacit knowledge" of course).
Best regards,
karsten
