When you smell something, that thing is actually inside you. You can say you smell a flower, but what you’re really smelling is some volatile molecules from the flower, and when you smell them they’re already inside your nose.

Likewise, when you hear, the sound waves must have already entered your ear.

Even when you see, what you really perceive is light hitting your retina, which is inside your eye.

But when you touch something, that thing is still outside of you. Technically, can also be said of taste if you lick something, but then there’s a strong likelyhood of some molecules of the thing entering your mouth as a result.

    You think your mouth is on the inside? Bad news, you’re just a donut. That mouth is outside your body.

    Hmmm no. Sound is pressure waves, not actual matter transference. Light, is sort of the same (ok, that’s a bit more complicated, but if we’re going to get into the quantum mechanics of it, touch is just based on waves of probability too).
    Conversely when you touch, there are lots of molecules that rub off and transfer. Some of those will embed into your skin.

      True, but the pressure wave is what is being perceived when hearing, light is what is being perceived when seeing, I never said what was being perceived had to be matter. In the case of touch, some molecules may enter the skin, but that is not the cause of the sensation. Even if you imagine an perfectly hard, smooth and clean surface that sheds no molecule, you should still be able to feel of you touch it.

      However, I thought about it after making this post, but there also is a small amount of kinetic energy entering you when you touch something, and that may be what triggers your nerve… So I guess even in the case of touch, it remains true that you can only perceive something that’s inside of you.

    When you touch something it’s nerves that make the perception possible, which are inside of you.

        The Light is what is being perceived in that example. The point of mentioning that the retina is inside the eye is that it means light must be inside the eye too when it hits it.

    Fyi, “obstrusive” is not a word that exists. I think you were trying for “obtrusive” but actually needed the word “intrusive.”
