Despite my advanced years, I am very new to (formal) philosophy. In the bit of recent 'dabbling' which I have done, I have come across statements like -
Nowadays, of course, the ideas of xxxxxxx are considered erroneous ...
The theories of xxxxxxx on mind/thought/belief/knowledge are no longer acceptable ...
xxxxxxx's ideas are no longer considered to be valid
What I am wondering is, in the light of these types of statements, is there a point in going into the History of Philosophy?
