An insect's "thinking" consists mostly of following instincts and some acquired reflexes. There's (much, much) more to the human thinking than that, and there are a few levels of consciousness in between.
If you'd stuck to that in the original post, I would've upvoted and moved down the thread. I was replying to the stronger claims that things like other advanced mammals "all think in essentially different ways", and your characterization of the nature of human thought.
