Answer:
- Ptolemy is, without doubt, the greatest figure in ancient astronomy.
- He gathered up the wisdom of the philosophers who had preceded him.
- He incorporated this with the results of his own observations, and illumined it with his theories.
- His speculations, even when they were, as we now know, quite erroneous, had such an astonishing verisimilitude to the actual facts of nature that they commanded universal assent.
Step-by-step explanation:
These are the four statements that the author makes that show that he believes Ptolemy to have been a remarkable and commendable figure. In this text, the author talks about Ptolemy and his work and discoveries. While the beginning of the passage shows an objective view of Ptolemy, the middle section is more subjective and expresses the deep admiration that the author had for this person. The author conveys this through the use of words such as "greatest," "wisdom," "illumined" and "astonishing."
