The presumption is against it, but it must be admitted to be possible.

It seems a forced and unnatural position to suppose that the disciples would go to one set of authorities and the master to another, and equally unnatural to think that a later critic, like Hippolytus, would confine himself to the works of these disciples and that in none of the passages in which quotations are introduced he has gone to the fountain head.

We may decline to dogmatise; but probability is in favour of the supposition that some at least of the quotations given by Hippolytus come directly from Basilides.
Some of the quotations discussed in 'Supernatural Religion' are expressly assigned to the school of Basilides.

Thus Clement of Alexandria, in stating the opinion which this school held on the subject of marriage, says that they referred to our Lord's saying, 'All men cannot receive this,' &c.
