Patience

'And obey Allah and His Messenger; and fall into no disputes, lest ye lose heart and your power depart; and be patient and persevering. For Allah is with those who patiently persevere.' (Quran, 8:46)

Reason

'I am and always have been one of those natures who must be guided by reason, whatever the reason may be which upon reflection appears to me to be the best.'
Socrates, in dialogue with Crito.
