While I understand the pedantic argument, (hey, I've read my Hume), I mean that I don't rely on my "perception" as is, but try to form it based on evidence, facts, numbers and other stuff from the "unattainable reality".
Reality might be ultimately unattainable, but a, say, DNA test for example can show with 100% certainty who the raper is or isn't. And a educated rundown on the numbers, performances, etc, beats perception, especially such as cultivated by PR and the media, anytime.
"""Besides, do you really perceive SAP as a cool company? """
No, but I also don't like "cool" companies. I could care less about the flavor du jour and "ramen to riches" stories. SAP is interesting in it's own way, and invaluable for tons of businesses using their system.
But that's the whole point. SAP is boring, and although that's actually good for them - it means they're reliable and dependable -, the TC guy is also right.
