Food for thought: the higher you go up the academic ladder, the more you learn about less. Thus you face the danger of one day knowing everything about nothing!
In primary school, you study a little of everything
In secondary, you study a bit more of fewer things - you are allowed to concentrate on either sciences or social arts
In bachelors degree you study even more about one subject - say, animal husbandry
In masters degree, you stud a lot about, say,chicken farming...and do research on feeding habits of chicken between age zero and 7 days
In PhD you research on the effect of iron mineral feed on chicken between age zero and 7 days.
Does that PhD make you a better chicken expert than the guy who stopped at bachelor's degree?
Perhaps some one should do a PhD to find out!
BTW: a professorship is NOT an academic qualification; it is just a rank in university teaching. Being a professor doesn't mean you know a lot; it simply means you have taught a lot at the university!
Nothing is real unless it can be named; nothing has value unless it can be sold; money is worthless unless you spend it.
