do you think Crusoe's father was right to stop him from going to sea?

I think his father meant well at the time. Crusoe's father has designed him for the law, but early on his head is filled with "rambling thoughts" of going to sea. No advice or entreaties can diminish his desire. His father gives him "excellent advice and counsel," telling him that only men of desperate and superior fortunes go abroad in search of adventures, and that he is too high or too low for such activities. Crusoe's father also knew he could not stop a young man from pursuing his passion. In the end Crusoe would go to sea regardless of what his father had wanted.
