Final answer:
The specific quote from Jakasta about what 'no man, ever ... mastered' is not provided. The related themes from the quotes suggest human limitations and the intrinsic difficulty in mastering destiny, morality, virtue, and wisdom.
Step-by-step explanation:
The quote from Jakasta that mentions what "no man, ever ... mastered" does not appear to be present in the information provided, and it seems there may be confusion with the character Jocasta from Greek mythology. However, considering the themes and the literary quotes shared, a response can be framed around the concept of human limitations and fate. For instance, the quote from Martial's Epigrams touches upon the powerlessness of humans in controlling certain aspects of life, symbolized by the riddle of the Sphinx, a creature that posed riddles to mortals and devoured those who could not answer correctly. The Epigram implies that human understanding and mastery have limitations, especially in matters of destiny and morality.
Moreover, the words from Hobbes describe a state of nature where humans live without society's benefits and are subject to continuous danger and the whims of a brutish life. This aligns with the notion that humans cannot master the force of nature and are intrinsically vulnerable.
Lastly, Confucian quotes explore the philosophical view that wisdom and virtue, while aspirational, remain challenging for most to fully master. The acknowledgment that change is essential and frequent failure part of the human condition further emphasizes that mastery over life's circumstances and oneself is an ongoing struggle.
