If the patient gives no sign and no symptoms,disease is incurable,master kent says,why?

Homoeopathic line of approach is based on symptomatology. Even diagnosis itself-- not an essential part for making a homeopathic prescription. Our entire assessment of the case depends on symptomatology-- according to Hering's law & its detailing as 12 observations of Kent.
If pt doesn't says any sign n symptoms thn we can't treat them as accordingly .... if sing n symptoms not present thn how can we rich to the right medicines ...we hv to treat pt as a whole so pts narrations must needed to form complet totality...
Because disease is manifested by sign and symptoms and if we don't have any sign and symptoms than on which basis we will prescribe medicine, so that it's impossible to cure a case for us.
