These are some notes which I wrote down in the last few months. I was thinking of writing a book, so I wrote in order to make the topic of my book a bit more clear. This is the only use of this text – to make it clear for myself what I am supposed to write about in my book. The only result of writing everything found here, which I would acknowledge, is that the title of my book should be ‘Reason, Language and Actions’. Nothing else should be taken seriously, nothing is worth mentioning etc. I did not proofread the text for grammar mistakes. If you want to take a look at it, you’re on your own.
