I used to think that we needed language to think but then babies and animals can think and they don't have a language. I then came to the conclusion that they may not have a verbal language like ours but they use their other senses to have a language and that's why they can think. So would it be possible for a person who had none of the five senses to think? And if we use our senses to think, do plants think? Plants have senses so can they can think to some extent?
