The division of the sciences into specialised branches

Adopted from the book : "The Principle of Ijtihad in Islam" by : "Shahid Murtadha Mutahhari"

The division of the sciences is the result of their development, but also its cause. For a science gradually progresses until it reaches the point where it is no longer possible for a single person to investigate all the problems it raises. It must then necessarily be divided up into branches of specialisation. Thus the division of a science and the creation of branches within it is the result and the effect of the development of that science, while, at the same time, more progress is made when these branches are created, and thought can be concentrated on the special problems in each branch.

In all the world's sciences - medicine, mathematics, law, literature and philosophy - branches of specialisation have been created, and for that very reason progress has been accelerated in each of these branches.
