Virtually all experimental psychologists now accept that our behaviour can be affected by stimuli of which we have no conscious awareness. Such effects are typically not very dramatic even though they are reasonably reliable. However, such results do not on the surface appear to offer much support to claims of profound and lasting behavioural changes brought about by subliminal advertising or subliminal self-help tapes.

The character of our perceptual experience is such that it appears to be integrated or unified across different senses. If introspection were all we had to go on, we wouldn’t distinguish different senses at all, but would take ourselves to have a single sense and to simply perceive, but not see, or feel, or taste, etc.

There is a serious flaw in The Terminator which pretty much ruins the storyline. The problem is about Kyle Reese, who must enter the time-displacement equipment in the future, sometime after the Terminator had already entered it. We call this the “Bad Timing Problem”.

I think we’re all at our most philosophical when we’re teenagers, aren’t we?
