What are the “dimensions” of power to which Lukes refers? He begins his account with the treatment of power provided by the pluralist tradition of American democratic theory, including especially Robert Dahl in 1957 in “The Concept of Power” (link). This is the one-dimensional view: power is a behavioral attribute that applies to individuals to the extent that they are able to modify the behavior of other individuals within a decision-making process. The person with the power in a situation is the person who prevails in the decision-making process (18).
