Clause 1(d) of Regulation 834 stipulates that an injury of a serious nature is a "critical injury" if it involves the fracture of a leg or arm but not a finger or toe. The Ministry of Labour interprets this provision as including the fracture of a wrist, hand, ankle or foot – . any such fracture would constitute a critical injury if it is of a serious nature. While the fracture of a single finger or single toe does not constitute a critical injury, the ministry takes the position that the fracture of more than one finger or more than one toe does constitute a critical injury if it is an injury of a serious nature.
Critical thinking of any kind is never universal in any individual; everyone is subject to episodes of undisciplined or irrational thought. Its quality is therefore typically a matter of degree and dependent on, among other things, the quality and depth of experience in a given domain of thinking or with respect to a particular class of questions. No one is a critical thinker through-and-through, but only to such-and-such a degree, with such-and-such insights and blind spots, subject to such-and-such tendencies towards self-delusion. For this reason, the development of critical thinking skills and dispositions is a life-long endeavor.
