"There is no sea more dangerous than the ocean of practical politics none in which there is more need of good pilotage and of a single, unfaltering purpose when the waves rise high"

This quote by Thomas Huxley is a metaphor for the treacherous waters of politics. He is suggesting that navigating the waters of politics is a tough and harmful job, and needs a strong and figured out leader to guide the method. The "good pilotage" and "single, unfaltering purpose" are necessary to guarantee a successful journey. The "waves" represent the different barriers and obstacles that emerge in politics, and the need for a strong leader to stay concentrated and identified in order to conquer them. Huxley's quote is a suggestion of the significance of having a strong leader in politics, and the need for them to stay concentrated and determined in order to prosper.
