How Filosophy defines it and the contribution of the Neurophysiology

Another area that has also defined the word habit is philosophy. And it is interesting the point addressed by the authors Rickaby and Moral, who comment that it is the effect of repeated acts and the ability to reproduce them.

It can be defined as "a quality difficult to change, by which an agent, whose nature is to act indeterminately in one way or another, is easily arranged to follow this or that line of action at will." This gives us a position that differs from the investigations that Donald O Hebb has done, which, in his work related to the organization of behavior, affirms that experience modifies cortical connections, so that even the brain of a Adult person is constantly changing in response to experience.

How many of us think that the actions we do and define them as habits are impossible to modify or change, but, if we look at Hebb's research, we will understand that, perhaps, that idea is not so true from the point of view of organic capacity that people have; as observed in Hebb's investigations.

Does knowing this information change the position you have in relation to habits? Are they modifiable or not?
