بَدِيهِىٌّ بديهى بديهي [ Intuitive knowledge;] such that its origination does not rest upon speculation, and acquisition by study, whether it do, or do not, require some other thing, as conjecture or experience &c.; (KT, Kull;) so that it is [ sometimes] syn. with ضَرُورِىٌّ [and opposed to نَظَرِىٌّ]: and sometimes it means such as does not require anything whatever after the intellect has directed itself; so that it is more particular than ضَرُورِىٌّ: (KT:) as the conception of heat and cold, and the assent of the mind to the position that negation and affirmation cannot be co-existent, nor be simultaneously non-existent, in the same instance. (KT, Kull.) ― -b2- [And hence,] A mere simpleton or fool: but this is post-classical. (TA.)
