In chapter 4 of Mary Shelley's Frankenstein: What does Victor say is different about scientific studies as compared to other studies

On Chapter 4, Victor
says:

None
but those who have experienced them can conceive of the enticements of science. In other
studies you go as far as others have gone before you, and there is nothing more to know;
but in a scientific pursuit there is continual food for discovery and wonder. A mind of
moderate capacity which closely pursues one study must infallibly arrive at great
proficiency in that study; and I, who continually sought the attainment of one object of
pursuit and was solely wrapped up in this, improved so rapidly that at the end of two
years I made some discoveries in the improvement of some chemical instruments, which
procured me great esteem and admiration at the
university.

Clearly Victor wants to surpass his
own abilities. He is enamoured with science because in all other fields everything is
"said and done", according to his opinion. There is always something that can be mixed,
dissected, combined, refined, and done alternatively in a laboratory. Within the field
of science you can focus on living and non living things, on organic and inorganic
elements, the weather, the seasons, the past, the present, and the future. Anything that
can be studied in the world can be figured out through science. This is why Victor loved
it so much, and that is what he meant to say with his
statement.
