“Consider what a vast field of ecstasy opens before the imagination when one thinks of old china, snuff-boxes, Roman coins, arrow-heads, and flint implements. It is true that many of us are too 'superior' for these simple pleasures. We have all experienced them in boyhood, but have thought them, for some reason, unworthy of a grown man. This is a complete mistake; any pleasure that does no harm to other people is to be valued.
For my part, I collect rivers: I derive pleasure from having gone down the Volga and up the Yangtse, and regret very much having never seen the Amazon or the Orinoco. Simple as these emotions are, I am not ashamed of them.”
