Have you heard people talking about the 'mystery' that they love about themselves? Well! Don't take me wrongly, but that's utter crap! We don't like mystery. We like it because we get to unravel it. It's too damn poetic to sit staring at a mystery praising its beauty and never moving a limb. I feel we humans are born curious and our joy lies neither in absense of mystery or in its permanent presence. I think we just can't do without one or another mystery which we can rip apart into thousand pieces. We are like mice who just need something to chew, for their teeth (our curiosity) keeps growing all the time. On a philosophical note, I would say that 'curiosity' is the most godly virtue that we have got. It's that invisible thread pulling at which, by and by, which can reach God. It's the thing that frees pursuit of knowledge from the mundane issues of right and wrong, purpose, need, greed, and all. It's that which justifies knowledge and its pursuit without any crooked argumentation.
Many people have met frightful ends in order to satiate their curiosity. So many mishaps would've brought all crazy expeditions to an end hadn't man been so inherently curious.
