That of

[Erq]

Hello,

William James wirtes that "the ideal of every science is that of a closed and completed system of truth."
Now, can I substitute "the ideal of" for "that of" in the bold sentence and paraphrase it as "the ideal of every science is the ideal of a closed and completed system of truth."?
