The correct answer is C) is necessary to doing philosophy now.
The history of philosophy according to Ortega is necessary to doing philosophy now.
José Ortega y Gasset(1883-1955) was a renowned Spanish philosopher who believed that history began with the presence of conscious humans that were aware of their decision-making process. For Ortega, history is not limited to a constant succession of incidents, days, or events. For him, history was the correlation of human personal events. His most important work on this topic was "Toward a Philosophy of History."
