The loose talk of usually religious people disappeared to a great extent and was replaced by scientifically justified treatises. But it didn't take much time till the scientists, mainly physicists and mathematicians, took possession of the philosophy. They argued that philosophy would be a science just like the others. Actually they substituted thinking in a scientific and logical way by science as such, presuming that both activities are the same. Nevertheless one can explain it because in the modern culture the entire universe is made to a scientific affair.
Analytical science needs concrete objects.
If philosophy is considered to be a science she also is dependent on quantifiable information, like the other sciences. But for philosophy exists actually no information of that sort, just as little as for the arts. By consequence the modern philosophers are obliged to turn their minds to the numerous opinions of their colleagues. This provides them with much work that rightly can claim a scientific status. Now philosophy has become 'the science of philosophy', which has everything to do with cleverness and ability, but nothing with intelligence.
