And all this time, I thought this inspired and documented the start:

“I wish either my father or my mother, or indeed both of them, as they
were in duty both equally bound to it, had minded what they were about
when they begot me; had they duly consider’d how much depended upon what
they were then doing;–that not only the production of a rational
Being was concerned in it, but that possibly the happy formation and
temperature of his body, perhaps his genius and the very cast of his
mind;–and, for aught they knew to the contrary, even the fortunes of
his whole house might take their turn from the humours and dispositions
which were then uppermost;–Had they duly weighed and considered all
this, and proceeded accordingly,–I am verily persuaded I should have
made a quite different figure in the world, from that in which the
reader is likely to see me.”
