The use of travelling is to regulate imagination by reality, and instead of thinking how things may be, to see them as they are.
Samuel JohnsonProvidence has fixed the limits of human enjoyment by immovable boundaries, and has set different gratifications at such a distance from each other, that no art or power can bring them together. This great law it is the business of every rational being to understand, that life may not pass away in an attempt to make contradictions consistent, to combine opposite qualities, and to unite things which the nature of their being must always keep asunder.
Samuel Johnson
