Not scratching your nose, breathing, etc. But Descartes adopted a large definition, which, if you think about it, is reflected in
untermensche's definition.
There are also plenty of words for what computer's do (computation, calculation, text edition, simulation, etc. etc. etc.). Where is the need to redefine the word "thinking" as what computers do? This is hubris. Scientists are human beings, if they think they can escape human nature merely by being scientific in their outlook they are wrong. I suggest some of them should try to visit their nearest church to ask the Lord for forgiveness even if they don't believe in God. Works even without a God this.
