If you want to know the weight of a wine glass, you can use a scale. Yet for the wine’s taste, you have to use your tongue, aka the sensory analysis. Still, are there really such two different types of quantities, one that is purely physical and another that is the sensory type? Here, we argue that instinctively designating certain materials attributes as sensory perceptions is unnecessary, considering every scientific concept has (in essence) originated from experience of our sensory organs/brains, i.e., all quantities were initially human perceptions.
