Of course philosophers are normally shaped by their times, their dispositions, their hangups and so on.
This doesn't mean philosophy per se is shaped by any of these things. It means that when a philosophy has been shaped by the above, it is distorted. It's incorrect.
The task of philosophy as a field is to overcome these flaws and obstacles. The best philosopher is so shaped the least.
But then, philosophy as it applies to any particular time and place is also partly a function of that time and place. If you take philosophy to mean not the generating function but the actual answers it gives, then it's a good thing for it to be shaped for the dispositions of the questioner.
