Amit asked:

‘If the things in our world changed their size randomly, we would have no interest in rulers or in measuring things.’

It is the answer given for one of the question.

I got answer that Philosophy is the study of general and fundamental problems, such as those connected with existence, knowledge, values, reason, mind, and language.

These things also changes with time and place so why do we have interest in philosophy?

Answer by Shaun Williamson

You assume that these things change with time and place but you don’t know that, not without investigation. I don’t agree that knowledge, values, reason, mind and language change with time and place in a way that effects philosophical truth.

Philosophy is about truth and truth isn’t relative to time or place. Belief may be relative to time and place but belief isn’t the same as truth.
