By 'intrinsic' we mean simply that there exists an established convention according to which one side is considered 'top' and the other side is considered 'bottom'. Usually the two sides in question can be reliably distinguished from one another. For example, by convention, the 'top' of a <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViZ9JwpEbGdrcN5Y29ycA" class="cyc_term">Table_PieceOfFurniture</a> is the side on which other objects usually rest, while the 'bottom' is the side which usually touches the floor. Notice that a conventionally distinguishable bottom and top do not necessarily imply a left and right, or a front and back. A plant is a good example of the case where they do not: top and bottom can be reliably distinguished but not, ordinarily, front and back or left and right. Notice also--and this is crucial to the whole conception--that while a <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvmLypJwpEbGdrcN5Y29ycA" class="cyc_term">TopAndBottomSidedObject</a> may well have a preferred orientation, changing this orientation does not change what counts as 'top' and what counts as 'bottom': if a car flips over on the highway its top is now facing the pavement and its bottom--the undercarriage--is now up in the air. If an entity does not obey this rule then it does not, generally speaking, count as having a distinguishable top and bottom--example: an hourglass or a book.
