"All science tries to reduce the diversity of things in the world to mere differences of appearance, and treats as many things as possible as variants of the same stuff."

"A 'logical picture' differs from an ordinary picture in that it need not look the least bit like its object. Its relation to the object is not that of a copy, but of analogy."

"Syntax is simply the logical form of our language, which copies as closely as possible the logical form of our thought. To understand language is to appreciate the analogy between the syntactical construct and the complex of ideas, letting the former function as a representative, or 'logical picture,' of the latter"

"The reason people are afraid of abstraction is simply that they do not know how to handle it. They have not learned to make correct abstractions, and therefore become lost among the empty forms, or worse yet, among the mere words for such forms, which they call 'emtpy words' with an air of disgust."

	# The UNIX find command can locate files based upon the time the files were last changed, accessed, or modified using the -ctime, -atime, or -mtime respectively. So, to find all files in a directory that are older than 7 days might look like this. (source: http://ddiguru.com/blog/72-how-to-find-files-older-than-7-days-with-unix-find)

	find /home/myuser -mtime +7 -print

	find /home/myuser -type f -mtime +7 -print0 #The -print0 argument will enable this search to find files in that path that may contain spaces in the file names.
