Detail:

The book Candide is written by Voltaire and is a satirical attempt at polarizing optimism and pessimism to extreme extents. The central character in the novel is schooled in the optimism which allows him to look at the positive side of everything. The line at the end, "let us cultivate our garden, is a summation of the entire events that have unfolded due to Candide’s relationship with the Baron’s daughter and his expulsion from Westphalia as a result. The eviction set into motion a turn of events that took Cardide on a journey across the world and therefore kept him from idling and letting his character grow stale. The term is used here as an analogy which is linked to the perception that when God created the heavens, he let man into it to dress it and beautify it with his actions on a daily basis rather than just acting as scenery, hence idling and doing nothing.
