I used the filter function for ex 1.3 sicp . But it fails for equal numbers.Please help

The problem is I can't seem to think of a way to do this without a lot of conds which I think is ugly. I used filter because I think it is better than using conds. What other ways can I do this in?

(define (mini c list) (if (null? (cdr list)) (smaller c (car list)) (mini (smaller c (car list)) (cdr list))))
(define (min list) (mini (car list) (cdr list)))

LISP (noun):
An ancient programming language used by aspie neckbeards to show off their proficiency while not realizing that it's actually shit

(define (smallest a-list)
  (cond ((null? (cdr a-list))  (car a-list))
        ((<= (car a-list)   (smallest ( cdr a-list))) (car a-list))
        (else (smallest(cdr a-list)))))

You can't use [m]fold[/b] or the dot in SICP 1.3.

Haskellish (foldl min (car xs) (cdr xs))
Damn, what else do I need to read beside SICP?
