| The conception of God and nature and of the relation of man to both provided the 18th- century philosophers with their faith in the worth and dignity of the individual man and the efficacy of human reason. The 18th century was the moment in history when men experienced the first flush and freshness of the idea that man is master of his own fate; the moment in history, also, when this emancipating idea, not yet brought to the harsh test of experience, could be accepted with unclouded optimism. Never had the nature seemed less mysterious, more simply constructed, more open and visible and eager to yield its secrets to common-sense questions. Never had the nature of man seemed less perverse, or the intelligence and will of men more pliable (yielding) to rational persuasion. Never had social and political evils seemed so wholly the result of ignorance and superstition, or so easily corrected by the spread of knowledge and the construction of social institutions on a rational plan. The first task of political science was to discover the natural rights of man, the second to devise the form of government best suited to secure them. And for accomplishing this high task, for creating and maintaining a society founded on justice and equality, the essential freedom was freedom of the mind. |
According to the last sentence of the first paragraph, ______ is true concerning "this emancipating idea".
A．the idea was yet to be tested through trials and errors of many
B．it was accepted with an optimism that has been cast with doubt
C．the people of the 18th century accepted it with great optimism
D．the people of the 18th century knew it from their own experience
