Words exist. What are they made of? Air under pressure?…

““Words exist. What are they made of? Air under pressure? Ink? Some instances of the word "cat" are made of ink, and some are made of bursts of acoustic energy in the atmosphere, and some are made of patterns of glowing dots on computer screens, and some occur silently in thoughts, and what they have in common is just that they count as "the same" (tokens of the same type, as philosophers say) say in a system of symbols known as a language. Words are such familiar items in our language-drenched world that we tend to think of them as if they were unproblematically tangible things - as real as teacups and raindrops - but they are in fact quite abstract, even more abstract than voices or songs or haircuts or opportunities (and what are they made off?). What are words? Words are basically information packets of some sort, recipes for using one's vocal apparatus and ears (or hands or eyes) - and brains - in quite specific ways. A world is more than a sound or a spelling. For instance, fast sounds the same and is spelled the same in English and German, but has completely different meanings and roles in the two languages. Two different worlds, sharing only some of their surface properties. Words exist. Do memes exist? Yes, because words exist, and words are memes that can be pronounced.””
